No you're not the only one. It's the cost and also the space I have or lack of. I wouldn't have any place to put it.
As far as cost, I don't have anyone else do the quilting either (my husband wouldn't understand that at all!) so I quilt my own quilts and would love to FMQ - will try that on the wall hanging I'm making now (on samples first of course). All my stuff has been straight line quilting so far.
