I really appreciate all the comments. I even spent some time looking at the 6300 which has a lot of the same features of the 6500 and 6600 (specifically the 9" harp). I just couldn't seem to find much info on the 6300. If anyone knows anything about it, please let me know. If I had the extra money I would probably go with the 6600 but with the encouragement from many of you I'll probably get the 6500. BTW, Annaquilts - great job! Beautiful quilt!
