I've seen some pretty nice quilt tops on ebay that sell very reasonable...check out the feedback on the seller to be sure they do a good job. It could be worth it to buy some of those tops, use your long arm machine to quilt them and then resell the completed quilt. I wouldn't sell one of my tops as cheap as some of the tops go for....way too much work and time invested plus the cost of the fabric. It's hard for me to part with any of my "babies" unless I know it's going to someone who will appreciate and care for it.
