I have been collecting a number of used tools from eBay and CL. I research what I am looking for do a search on eBay and CL and wait for a deal to come along. I have gotten some incredible deals on very expensive items such as machinist levels, parallel sets, indicators, V blocks... I just got 4 machinist clamps in two sizes along with two 1x2x5 parallels for $35. They are all in perfect condition with only slight amount of wear. This is all sterret stuff which would have cost hundreds of dollars new.
