Since you said you have taken many hours of workshops on quilting then you know this is what you want to do. Don't fret over the decision, just start on the new adventure and feel good about it.
I have room for one and can get one if I wanted it and always thought I wanted one, UNTIL one LA I know let me spend a day working/learning with her. I lost interest after the loading of the first quilt. That part was boring and tedious for me, everything about it was boring except the actual quilting part. I would have to hire someone to load the quilt and get it all set up and then I'd have the fun of quilting it.
