Personally, I would stick with the first 2, and pick up additional feet here and there... Ask if they will throw in a good 1/4" foot to seal the deal :wink:
The extra's the first two have, are ones that I use all of the time and they are very handy to have... I started out on a very basic machine that I had for years...I couldn't wait to get a few bells and whistles :D:D:D
