I bought the HTX-10 for $50 from a hamfest at the bottom of the solar cycle. I have a HTX-100 I bought for $30 from Radioshack on clearance (!!!) Nice little rigs.

btw you should troll radioshack from time to time. You will never believe the gems you get. In the early '00s I looked at the RS stores in NYC and found quite a few things. I even got a PRO-2080 trunk tracker base scanner for $20.
