hi guys, I have a 7100, $300.00 can't beat it, Get the 7100,save your money and but some accy's with it. The 7200 and 7300 don't have that much better running gear, at least I don't think so. I have no trouble with the grip shifters. Get the 7100 and if in a few years you think you need something else get it then, I can't justify the price difference. JMO
