Bobby, you are dead on with the craigslist for materials! I have been scanning it for days! The deals on there are insane! I recently bought a keyboard amp for my electronic drums off craigslist, this amp sells for $499 new, I found one on CL that was less than a year old, college kid had it listed for $200 and I got for $150! The set of electronic drums that I bought off CL, retail for $1100, I bought my set with a stool and a few other extras for $325 and they still had the shrink wrap on them. Plus the kid game me the receipt for them from Guitar Center from when he bought them 8 months earlier!
The deals on craigslist are insane! Over the past two years Every piece of musical instrument stuff I now own has been bought off that web site and for a fraction of the cost! I bought a full blown, top of the line Carvin PA system (thanks to my Dad). It retailed for $1900 total, I got it for $700 plus several cords/cables etc. that were worth another $200!
