I played one of these in GC a few days ago and am considering picking one up. However, when browsing eBay, I notice a HUGE difference in price between these. Some people are selling them for $650 new and others go for $1400 new. At least with Fender, they use "American" or "Special" in the name to tell what model is what. Can someone explain to me how to differentiate between them? Thanks!
