Is that the one that's around 800? If so, it has a wide feed dog plate that literally allows you to guide the fabric with one finger. I haven't used one yet but they seem to be flying out of our local dealer's store. Every time we have a class someone else has bought one. I'd love to have one just can't afford it right now. If you're near Danville Illinois go into Threads of Time and check one out. Talk to Bill, his wife Missy or any of the staff there and they'll be happy to help you. I know Mary has one that she's been using, she's only there Mondays and Tuesdays. They're wonderful people with a magnificent fabric store and retreat/conference center all in one. They're follow up service is great too.
