I guess I was dumb when I started FMQ'ing with my older Singer - didn't know any better so I just went ahead and did it. I still do it. You really don't need a fancy machine to do
any quilting unless you want "fancy stitches". I'll stick with my older Singer's. Right now my favorite vintage Singer for FMQ is my model 237.
Of course I would love a machine with deeper throat space. I'm drooling over a HQ Sweet Sixteen which is a 16" throat compared to the little throat space on my 237 - but - until I can come up with at least $5,000 for the HQ then my 237 works just fine.
I've also got 14 other vintage Singer's to choose from if/when I tire of my 237......
