Nice! That's why I love going to flea markets! Folks at work always ask me why I go to them or what I'm looking for when I go to them. Your post is precisely why I love going to them. You never know what you will find
I found a PRO-106 a few weeks ago at Radio Shack on clearance for $202 minus an additional 25% on all clearance items. I scooped it up right away.
Some of my finds at flea markets/thrift stores:
Kenwood Low Band 110W Two Way $15 (polarity protection diode-easy fix)
RS Pro-96 P25 Scanner $7.99 < No antenna - works perfectly. No lie $7.99 in a huge bin of TV remote controls !
(2) Standard-Horizon HX-370S VHF Marine+Land Mobile HT's good batts - $6.00 for both - Taped together with scotch tape. Like new.
A working Aircraft transceiver for $10.00
Two or three high end, fairly recent models Grundig Short Wave receivers for cheap. Digital displays/SSB
(2) BC200XLT Nice 200 chan conventional scanners with accessories
A multitude of other very nice analog scanners I saw but didn't buy.
It pays to drop in and poke around occasionally.
