Actually, about a year ago, I was passing through Boston, MA and happened to drop into their "banjo center". To my dismay, their "pro audio" room was stocked with the very stuff gearslutz is all about. They had Manley, Sony, etc...The salesguy did comment that this was pretty unique for banjo ctr.
We do have a few of the Pro Audio "business center" shops in the state. But they usually don't have a facility to try before you buy.
There's even a guy down here(shall remain nameless) who only takes cash!
