butterflyquilter,
be patient and wait for the next big show. all the venders are there and you can try them all out and compare. they will answer any questions and they are the most knowledgeable. you will see features that you never thought to ask about. sometimes, they will sell the sales model right off the floor at a discount. that's usually a really good deal. always ask about that. they sometimes don't want to ship them to the next show. they would rather sell them and be done with it and start out fresh. especially if the next show is across the country and they won't have time to break down and set up again quickly. so they can be having the next one setting up already while you're taking this one away. if you have transportation, no shipping. always ask.
