There is an accuquilt group by that name at
http://groups.yahoo.com that has a lot of good information about the Go! That's where I learned about Shopper's Rule. I put in a bid and got a go! from SR for $280 with free shipping. Also found dies and mats online for 20% off and free shipping. This made the system much more affordable for me. (Actually, I bought it for my disabled sister to use but I will be using it too.) Haven't had a chance to use it yet, but I am looking forward to it.
