...But the $699+ (plus extras) price tag is probably going to be out of my budget, unless I sell almost every scanner and radio I have...
Keep in mind the $699 price for the SDS100 is the MSRP/list price. The Uniden BCD536HP has the same $699 MSRP/list price but actually sells for much less. Using Scanner Master's current pricing as an example, their "regular " selling price for the BCD536HP is $559.95 and it is currently "on sale" for $499.95: Uniden Bearcat BCD536HP Police Scanner | ScannerMaster.com
I'm sure product availability, supply-and-demand and dealer competition will all play a part in the actual "street prices" that we see for the SDS100 especially when it is first made available for retail sale. Eventually I would expect pricing to be similar to the BCD536HP example above seeing that it has the same MSRP/list price from Uniden.
