Cary W--right now (through this weekend I think) Accuquilt is having a sale on their cutters and dies--it's their big annual sale and probably best of their sales. Think both the Go and Go Big are reduced by $150, and dies 20%off, Qubes $30 off.
I love my GoBig (although it's getting either repaired or replaced right now. I started with the strip die bundle and still use at least one of those strip dies every single quilt I make, especially the 2.5". I've found that beyond the strip bundle, I tend to buy dies as I need them or their prices gets slashed so much I can't pass up. Be sure to register them on the Accuquilt website so you have a complete list to avoid duplication (although that does sometimes happen)Also, be sure to check out the website for learning videos--which sometimes you have to put into the search box to get (i.e. to cut bias binding).
