ok, I'm going to chime in, so the op wants a scanner, my best advice is to go for a 325p2 or 996p2 or the 436 or 536, if they work great if not move up the list till you find one that works, now where I live its analog but these fine folks here told me if I ever get digital I better be prepared, so I have a 536 at home and 436 on the road, I have tested my 436 as far as Oregon, works great, my favorite feature of the 436 is it takes AA batteries, same goes with the 325p2 and the other handheld, I'm skeptical about the sds 100 proprietary battery.
but the main thing is if your traveling you need to look for the features you need in a scanner and get that as it will be your scanner.
