Great info. I have a nice, large space for the machine so that won't be an issue, I like the idea of self-servicing it. I have rented at my LQS and used a Gammill and an Innova. Both were computerized and I really liked that. I'm probably going with a used one for the cost savings.
I'll check out Longarm University. I live near Mpls so would like to get one not too far away.
Anyone have any issued buying a used one?
