I have the MC6600P - and it's at least 14 years old and going strong. It's easy to use and stitches out great. Very easy to change the stitches too. The only issue I had was the needle threader wasn't working and so I took it in and had it serviced at the same time. It gets serviced about every 4 to 5 years. I learned how to clean it myself so it doesn't need it any more often. I didn't know there was a 6600 and a 6600P. When I bought it, it was the only one the store had and it was on sale with the set-in table. (I do not like using a portable on a table top if I don't have to.)
