I have the Juki TL98QE, which doesn't have the extension table. I paid 700.00 for it in 2008. It has never been in the shop. I try to keep it oiled, per manual. I have quilted lots of quilts on it. I don't have a frame, no room for that.
I would buy another Juki without thinking about it.
Sounds like a good deal for the machine alone.
