I am not in the market, but if I was my first choice would be something that does the job but not tak much room. I have my eye out for this:
http://www.apqs.com/machines_george.php
or
http://www.quilttrends.com/hq16.asp?...FYKB3godwlb4RA and go to the link that reads Sit down Version
I like to move the quilt rather than the machine and these smaller machines are more appealing to me.
Hope this helps,
Maria
