I will complain about the price of stuff, but if I see something I really want, I don't really have much of a limit. Well, not 250K vintage LP and dumble combos, but if I play a 5K guitar I love, I will just buy it. I'm no pro musician, and I might just buy it to look at and hack on, but I spent a long time in school to get what I have, and the ability to get what I want. Of course, I have kids, college funds, braces, retirement, etc, so I am pretty much self regulating on costs. I guess that is the constant mental battle of most of the adult members here...you can, but should you?
