If your seriously thinking about it get the GO instead of the baby.. you are limited on the dies you can use with the baby... But you can use ALL dies with the GO... however you cannot use the studio dies with either....
thats MHO.. and buy extra mats, they are for the most part 'disposable' if you use your machine as often as I do..
I just got some really great priced dies from the fabrichut.com thru amazon..
