I got mine because I wanted it but didn't think I really needed it. Didn't think I'd use mine much since I don't got to retreats or do classes. But it's come in mighty handy. I have a sewing space in the basement where I can work while doing laundry, etc. and the FW can be taken downstairs easily. Also, when my Viking is set up for FMQ I can piece on the FW. Back upstairs with no problem. Once a month, sometimes more, I help with my elderly parents who live out of town. Along comes the FW. It's surprising what you can get done by sewing a few seams in between cooking, cleaning, etc. I've finished three quilt tops and have two more in progress that I've worked on mainly during these visits.
So I'd say, yes, go ahead and get the FW. If for no other reason, they're just so gosh darn cute!
