I've been staying quiet on the subject for several months now. But it's time to speak out again. I'm in S.E. Michigan, Macomb County, Macomb Township, Michigan near 25 Mile & Romeo Plank Rd. I currently own one SDS200 and two BCD536HP's and they all work perfect. Side by side I can't tell the difference! Same goes for Uniden's BCD436HP, BCD996P2, and Whistler's TRX-2, and Radio Shack's PRO-197. This is from my home office using the stock-supplied antenna indoors. Now if I go mobile it's a different story. There are numerous areas that will work ok, but not while driving, only stationary.
I have two friends in Washington Township, Michigan near Van Dyke Rd and 29 Mile Rd using Whistler WS-1098 and they're completely satisfied.
So my advice is try and borrow one from a friend to try before you buy, or buy from a reputable dealer that will allow you a full-refund if you're not satisfied and can return it. If it works you'll save a couple hundred bucks. In the future if your situation/location changes you might wish you bought a SDS200.
