I havent been 2nd hand shopping in a while, but the best find for me has to be DBX-Alien EP on Peacefrog. The sticker looked like it said 3 pounds, but the guy at the counter said 5. When I told him 'Oh, that looks like a 3', he didnt argue and sold it to me for 3. A bargain.....and I've been offered a lot more for that record ;)
