Thanks everyone...I'm glad to hear that the 6600 isn't a real problem with fabric getting caught on the built in walking foot as I would have preferred it over the 6500, although both look good machines. I think I will ignore what the lady in the shop said about their quilts catching on it. I'm still hankering after the 7700 though so I will bide my time a bit longer and see what happens. If not that, then probably it will be the 6600...at this stage :)
