OK guys, here's what I'm basically trying to figure out. Tomorrow, I'm going to this little shack in NJ called "Pianos Plus" to buy a Yorkville XM200. The amp, from what I hear around here, and a brief experience playing with it, is great. But now that I've talked with my folks a bit, they are a little concerned that even if I will get a cheaper price ($400, $399.99 techically) that a small music shop like that can take away my cash and I won't be able to do anything about it if there's some sort of problem. I've talked with friends a little, and they say that so long as you have a warranty from the manufacturer (which will replace the item if damaged etc) and a reciept (so I can return it if it grows on me the WRONG way) that I should get by fine. I've talked with the guy who runs the business and told him I was interested in it for a tone and volume upgrade, and he basically said "sure, bring over your drummer and jam loud for a while." It didn't seem like I'd have to worry about getting ripped off, but I'm still wondering. Any Precautions you guys think i should take with buying from small instrument shops? Also, what about them being a registered dealer?
