suzanne, i want the pasta attachment SO BAD!!!
havent caved yet but i think you just enabled me!
Oh let me help enable you!

I have the pasta rollers and cutters and love them. My nieces had a blast helping me make pasta with them. I only use them a few times a year, so they were a bit of a spurge, but I got them when KitchenAid had a 25% off all accessories rebate a few years ago.
I also got my KitchenAid 600 pro on a $50 rebate from amazon, for $300, so I got quite the deal at $250 with shipping after the rebate. I love the 600 because when I do bake I like to do a fair quantity at once.
The colors were limited at that price, but I wanted the medium grey (sorta gun metal) anyway. So see what you can find at Amazon (or wait for a 30% discount code at Kohl's).
One more note, I have heard the ravioli rollers aren't worth it. Typically rolling the dough into sheets and cutting them with a pizza cutter after pressing between your "lumps" to seal them is actually easier and works better. But, that's just what I've read, I have no experience with them to back that up.
