I mean wouldn't it be nice to deal with the stuff you love? I think about it quite often, but then come the doubts, cost of dead stock, the slavery deals of manufacturers (you wanna have stock of that nice guitar, you gotta take also the lemons, etc.), the dudes that annoy you for hours with the latest thrash riffs and then go off and buy on ebay, low margins, high rent costs, shop lifters/theft, etc.
But still, wouldn't it be nice to make some people happy with nice guitars, amps and stuff?
