I'm a brand new quilter and just bought one. I really like it so far. It definitely helps me be able to manage the fabric a bit better.
I ended up getting the sew straight seam guide. I'm having a bit of trouble getting it to be completely flush with the table. The suction cups make it just slightly off the table - enough that the fabric slides underneath, defeating the purpose of the seam guide. Has anyone else used those? I was thinking of just getting some tape and taping it directly to the table. But, like others have said, I have to move everything when I need to get to my bobbin.
