In my opinion, most men would want more than one of anything, if they could afford it. Be it guitars/pedals/amps or cars/electronic gadgets/even women, there's an innate propensity to want better, more and/or different. It's usually just a matter of what the costs are.
I'm stating "men" in particular, cos I believe a lot of men project their carnal desires onto their guitar spending/trading habits heh. I guess females could also not be all that different - shoes, handbags, dresses, what have you.
