I don't know anything about the Baby Lock but just from looking at their
brochure online it seems to have a much smaller throat than the Janome 6600.
It does not have the accufeed system that Janome has.
I think you get 14 feet on both machines unless he is throwing a few
extra on the Baby Lock. I've had the Janome 6600 for 4 years and
never had any problem. Never been serviced either. I try to take
good care of my machine and make sure to clean it regularly.
Lots of quilters here have/had the Janome 6600. Some have
upgraded to the 7700, 8200 or 8900.
Test drive a few machines and see what you like. Also make
sure the dealer offers classes. Are there other dealers within
driving distance? I really like my dealer because she didn't talk
me into buying anything. She asked me what I wanted then
showed me what would meet my needs and let me try the
machine I was interested. Of course I had my mind set on
the Janome 6600 before I walked in the store. LOL
