My only great find was free, in a recycle metal dumpster. I was walking by this dumpster and a saw a bike laying on top of a heap of metal with more metal on top of it, didn't think much of it and kept walking past it. I went to a business there to do something and was walking back when I decided to have a closer look at the bike see what kind of junk it was. It was Kona Lava Dome with all Shimano SLX components, and it didn't look that bad. The seat was completely wore out, as was the rubber grips, the cables got torn maybe from being in the trash, and the pedals were bent on one side., but everything looked ok just dirty. Took it home, stripped the bad parts off and put new ones on, put a new chain on since the old one was rusted, adjusted the spokes and put air in the new tires that it had on out of the dumpster, washed it, waxed it and it looks brand new. I found on a web search that the model was only 3 years old when I found it last year. It works great, didn't have to do anything to hubs or bottom bracket, just replaced the bad parts and rode it. It's now my go camping trail bike while the other one I had is now my wifes. Dumpster plus about $80 in parts got a 3 year old $800 bike.
