I would not advise purchasing from Zip. Other members here on Radio Reference have had mixed experiences with Zip. Some had no trouble at all. But others had a number of issues that the dealer should have resolved, or at least assisted, but Zip just ignored them. In most cases, Zip charges more for accessories, such as the upgrades for DMR & NXDN, than other dealers. Of course, you should not buy these from a dealer, as once you register the scanner on Uniden's site, they are by far the cheapest. For the DMR upgrade, Zip charges $99.99. ScannerMaster is at $75.00 But, once you register your scanner on
MyUniden, the cost is $60. The NXDN & ProVoice upgrades are $50 direct from Uniden. ScannerMaster charges $75 for each of these. Zip is at $89.99 for NXDN or ProVoice. I would not purchase the ProVoice upgrade. That format is no longer supported by the manufacturer. All but a few systems that used to be ProVoice have migrated mostly to P25, which is supported by default with the scanner. No upgrade needed for P25.
I'd also advise against paying a dealer to "setup" or "optimize" your scanner. That's not much more than updating the database for you, and adding any firmware upgrades, if needed. That's easily done by you after installing
Sentinel on your PC. I also would avoid paying for a dealer to program your scanner for you. That's usually around $40 for one county. Additional counties add to the cost. But all the dealer is going to do is add the systems Sentinel shows in your county. Again, once you install Sentinel, you can do that yourself. To get started, you can have the scanner use the main database, and load systems near you based on location & distance. After updating the database in Sentinel, by letting it connect via the internet, you can start listening. You can have Sentinel create a Favorites list for you, if so desired. But there are a large number of "how-to" videos on YouTube showing you how to create a Favorites list (programming) for your scanner.
You don't show your location in your profile, but in many cases, if you ask in your state's forum, you may find someone in your area that will share a programming file to get you jump started.
You'll need Sentinel installed to maintain the database in the scanner, as well as apply any firmware updates that might be released. You can have Sentinel create a Favorites list for you, based on your location & desired range. Or, use Sentinel to append frequencies & systems from the database in the software. Third party software, such as ProScan or ARC536, will let you import systems from the RadioReference database if you become a Premium Subscriber. That allows you to customize what you want, without a lot of "extra" channels that are not of interest. ARC536 is $35.95 from ScannerMaster for the Basic version. The "Pro" version, which adds an option to control the scanner via your PC, is $62.95. (Those costs are if you download the software for installation. If you'd rather get it sent to you loaded on a USB flash drive, add $9.00. My choice for programming, though, is ProScan. At it's $50 cost, that includes the PC control option as well as programming & logging activity. ProScan also can be used on a large number of other Uniden models. See the
ProScan website for a list of supported scanners. The ARC program can be used only on the SDS100, SDS200, as well as the BCD436HP & BCD536HP models. You can download & install Sentinel before you get, or even order, your scanner, That way, you can 'test drive' it & start getting familiar with its uses & capabilities.
The Easier to Read
manual is more 'user friendly' than the Uniden manual for the scanner, though either one can answer many of your questions and concerns. Don't overlook the Wiki page for the
SDS100 as well as the
FAQ page for the SDS100 & SDS200.
As
KB4REA and GILLIG40 have noted,
Main Trading often has special deals. You might need to partially go through the ordering process, adding the scanner to your 'shopping cart' to see special pricing, but you can bail out from that screen with having to immediately order.Whoever you buy from, consider shipping costs if they charge extra for that. Quite often, if someone runs across a current 'sale' from one of the dealers. they'll post that in a thread in this forum category.
I've had my SDS100 (as well as the SDS200) since they were introduced in 2018. It works well on the multiple simulcast systems here in the DFW metro area.
