Do a search on the Accuquilt (see search option at top of page) and you will find some recent threads with good info.
I have a Go! and like it. The company recently lifted its bans on advertising for less than retail, so it's possible to find some really good bargains on the Go! and dies online.
I also advise joining the accucutquilters groups at htt://groups.yahoo.com ; lots of good info there too.
