Well, I gotta say I wasn't exactly a hard sell when I got my bonneville (more like threw the cash and grabbed the keys) but Motoprimo in Minneapolis is very friendly (ask for Zack) and they'll make time for cash strapped youngsters, not just the better off riders.
I'll be due for my 500 miles tuning pretty soon and then I'll have a better idea on how good they as with Triumphs (they also sell Guzzi, Yamaha, Ducati, MV Agusta, and Suzuki)
Also, they have some real cute sales girls who really know their stuff

:-D
