Do any of you have the "Flynn's Multi-Frame Quilt System"?
I'd been eyeing it for a while, and then took the plunge when I saw it half price on craigslist.

Currently, I've got it set up, and working on getting some quilting done on the quilt in the frame, but I keep having the problem of my needle coming out.
So far, I've had to buy a bunch of different length pipes for it, along with a couple more of the red roller things (the ones I got are black).
Any tips or hints for a newbie with it?
