You might want to join the homequiltingsystems group on groups.yahoo.com . It's very large and very active, and the posters have a wide variety of longarm and midarm setups. One of the topics I have seen talked about there is how some people bought a longarm and then were so intimidated by it they let it sit for a year. I'm sure buyer's remorse would be an interesting topic to bring up there.
How much research did you do before purchasing? The rule of thumb advice on the group above is to spend a full year doing research and trying out as many setups as possible before making a purchase.
