I just brought mt sweet sixteen home last weekend. It is a considerable expense - I had to save for quite a while and then had a hard time letting go of the money!
I love it. Have been practicing this weekend and krnow it was the right decision. I have been doing free motion on my little machines but it is hard on my arms and shoulders to do that. So I am not too far from beong pretty good on the 16.
Only you know if it is worth the drive but if you go you will love it!
