I'm glad I could help! And I agree with SewandSow, adjusting the height often would be a pain in the butt. I haven't adjusted the height on mine since I put it together. I looked at the other tables, like the Gidget and SewEzi, but I wanted something super solid - and the SewPerfect is exactly that. You can also use your knee lift, if that's something your used to. I also use the measuring tape sticker on the front edge of the table way more often than I thought I would.
My problems with quilting are more related to the amount of patience I have and less related to my machine, lol I've done a queen sized quilt (and I did that as a quilt as you go!), and decided that I wasn't going down that road again. It was too fiddly and such. At this point, I'm researching and saving for a longarm.
