I guess it depends on your personal preference. The SDS100 and SDS200 seem to be remarkable scanners, especially in dealing with simulcast trunking interference. Many of the posters here seem to really like having the scanner on their person most of the day and listen while they work or are out and about so many seem to prefer the portability of the SDS100. For me personally, I usually listen to my scanner at home or once in a great while have it in the car/truck if i'm travelling somewhere. So, for me the SDS200 would be my preference. As with any electronic device, all are subject to defects and flaws, i.e. cold solder joints, components cracking or breaking from the scanner being dropped. Just from observation on this forum though, it seems that I read of more issues with the SDS100 than I do with the SDS200. Perhaps it's because more people are using the SDS100 compared to the SDS200. I don't know. Both seem like the "Cadillacs" of the scanner world and perhaps one day i'll be willing to Pony-Up $700.00 plus for one of these two scanners, but for now, my Radio Shack PRO-668 (converted to a WS-1080) suits my needs just fine.
