Hey Mike,
I don't know of any VPI dealers in STL, Chicago would be the closest.
To tell you the truth, I've been considering selling my VPI rig (Scout/JMW9/Dyna10X5/SDS). (hhhiiisssssss, blashpemy). It's a great rig that I enjoy, when I've had time to listen, which has continued to decline over the last year.
I need to think about it, but you're welcome to drop me a line to discuss if you're interested.
In the meantime--somebody want to talk me out of dropping my vinyl?
Cheers,
Brad
