Checking in late on this thread to say that I am one of the lucky ones. The owner of my LBS knows that I come in trying to piece together old junk, and he has advised me on what works and what doesn't and let me pick through the junkyard in the back room for stuff. Most recently, he picked out a used 6-speed freewheel from one bin and a derailleur adapter hanger from another to help me get my daughter's Collegiate converted to index shifting. Between those two items, a new chain, and some advice as to which of the spare derailleurs and shifters I had in my stash would play nice together, I think I spent less than 20 bucks with him that day. I always try to be mindful of the fact that my nickel-and-dime stuff is not what's keeping his lights on, but rather selling and maintaining the shiny new units out in the showroom, and with that perspective I'm grateful that he's willing to spend any time at all on me. He also has an appreciation for older bikes and is willing to chat about the old stuff. The shop sits a few blocks from our downtown bike path, so whenever I have a new project out on a ride downtown and it happens to be during his business hours, I stop in to show it off.
