I've purchased both the SDS100 and SDS200 (and a number of other accessories) from Bearcat warehouse over the last few months and they were great. Not sure why there's been so much negativity about them in other posts. I've used their online chat a few times to check my order status and they've answered my questions within a few seconds. I've also called a few times to get more information on products and they were always helpful. It seems like the people working there are scanner enthusiasts. They seemed to understand my excitement (and impatiences) while waiting for a delivery. I've also bought a ton of stuff from Ham Radio Outlet (they are close to my house) and have had good experiences with them. I'm guessing you can have a bad experience with anyone.
