My understanding is that the pro is better for quilt stores where they have to cut larger sizes of fabric and cut more frequently. I have the alto 2, and I love it. I also cut fat quarters and sometimes other sizes, but I've even been able to use it to cut larger sizes by folding the fabric carefully and using a new rotary blade. See if there is anyone in the area who is selling it or contact one of the reps they have on the site. The price will probably be less expensive than thru the company online store. I bought mine at a local quilt show.
