I test drove a frame at the Des Moines Iowa quilt show in October. Didn't have enough money, but Plan on getting one when I go to Paducah.
The machine they had on it was an older Bernina and even tho the throat was smaller, the way the sandwich is loaded in it kinda moved with the machine. If I remember right, I did the are of a 12 inch block with no trouble. that's why i want to try it again at the show before I buy it
I already emailed them and found out where their booth will be. I want a big frame, but i am going to get a tin lizzie as soon as I can. this frame fits on a table and is 450 on the site but I know it was quite a bit cheaper at the show.
I don't know what kind of room or plans you have for the future, but it is different and the people are really nice.
BTW I am NOT affiliated with them in anyway.
