I just bought a LA. I used to rent one at the LQS near my old home. I have seen some lovely quilts done by others, but I prefer to do it from beginning to end and now we have moved to a home that has enough room for one.
I tried several times to quilt on my home machine and took some classes with several great teachers, but I make larger quilts and pushing the fabic through the machine, even with a smaller one, was frustrating.
As for everything, it's what works for you.
