My only problem with my FW is that the foot pedal sticks and has to fixed frequently. However, that might be MY problem, because I've had to replace the foot pedal on my last two machines. Other than that, I love my FW!
As for speed, who cares? I think using the FW is very calming, and my 1/4" seams are a lot more accurate with it than my Janome Heart Truth.
