I know this is an old post, but I too have the 6600P and love it. Only thing I miss is a freearm and I cannot for the life of me get the automatic threader to work. Otherwise, it came with extension table and all the accessories one needs. I love the needle down, auto thread cutter, knee lift, and teh Accu-feed. I think I paid about $1250 or so a few years back.
