I recently bought a Tiara II for the same reason . . .lack of room. However, I also purchased two extension tables for either side of the table that fold down when not in use. I absolutely LOVE this machine! I haven't quilted anything large yet, but have a couple of tops waiting. Right now, still quilting whole cloth until I get the hang of it.
One thing ong that turned me off when I was considering this purchase was the news that tension (lower and often upper) needs adjusting every single time the thread is changed, even if it's one color to the next in the same line! But once I got the hang of it, it's about a 90 second process. If you have a fair amount of sewing experience, knowing what needs adjusting and how, just comes naturally.
good luck with your decision
