I like the thinking man! I've been thinking the same myself of late. According to Slash's biography, he only had a crappy guitar, but skipped school and spent 12 hours or more playing every day.
I also often ask myself how many guitars I really need considering that I can only play one at a time. So I have decided not to buy any more as well. But it's hard not to look and want...
Good luck with it!! Stay strong!
