I have a Viking mega quilter with original inspira frame and SR. It was too good of a deal to pass up. I got the whole set up for 1000.00. I actually had been using the Viking as my primary machine. I have a singer 7426 and hate it! Too loud! So I sewed on the Viking for a year till I recently purchase a Juki F400 as my new primary machine. Finally I have the Viking loaded up on the frame. Last night was my first time to ever quilt on the frame. The first couple of hours were very very frustrating. Finally I adjusted the tension on the bobbin and it worked like a charm! So now I can finally quilt those tops that have been building up. While I would certainly rather have an 18" to quilt with this is far better than wrestling the quilt on the table. I would be so worn out after quilting for a short time. This is much much better! The way I see it, I could probably sell the set up today for more than I paid for it in the first place so it was a very good investment and I certainly am getting my money's worth out of it.
