I'd say go for it! You want one, and you have hubby's blessing. Tho do perhaps make a list of features you'd like to have, and look at a few machines. After you get one, you can do quilts for charity-they don't care about "perfect" quilting.
I bought a Handi Quilter, and I love it! Having it in my home helps with my stress levels and physical issues. I can walk away from the machine whether or not the quilt is finished. No guilt here!
