If you are going to buy one (and I want one sooooo bad!), check the prices from the dealers. I saw one advertised at Ken's I think for $4,000. I was in awe.
Also, I saw one advertised on QuiltersFleaMarket for $3,000, never been out of the box.
I'm renting one from my LQS for $15 per hour. I want to try for a long time before I invest that much.
