My dad and I are both guitarists... neither of us play out regularly anymore, and I've condensed my 'collection' way down.
He, on the other hand, has bought probably 50 guitars on ebay the last three to four years.
He's had a couple of bad transactions, where items came not as described. He bought an older G&L described as mint that was rough and not the same guitar pictured, and he bought a 1990s USA strat that had the factory wired pickguard pulled and replaced with something chinese/korean (ceramic bar 'magnets', cheap pots, etc).
He's also bought some guitars that showed up with perfect setups and sounding great. I'm currently 'holding' a mexican strat of his that is probably the best feeling and playing cheap guitar I've ever handled.
The third side of the coin, is he's bought a couple new/like new guitars that were just 'duds.' They were as described, looked good, were obviously genuine, but just had no mojo.
My advice to you is to buy the local guitar that you can put your hands on and know exactly what you're getting.
