I have the Cuttlebug, which is like the Sizzix.
I like the Cuttlebug better, because you can use any dies with it, from any manufacturer.
They are pretty cheap, too. You can get one at Joanns for about $40. BUT, the size is only 4 inches wide by usually 6 inches. I never use it for quilting, because I have a Cricut.
They do have a Sizzix "Big Shot" that does bigger cuts. I'm not sure how big.
How much is the Accucut GO? These would be an option if its really expensive.
I would get a Cricut, though, before either of them. The Cricut cuts everything. Fabric, paper, stencil plastic, vinyl,etc. And you have the option with it to use a computer program to completely customize your cuts or not use a computer and use their cartridges.
The sizes can go up to 2 feet! And you can do them bigger with creativity! LOL!
You can get a Cricut Create right now at Walmart for around $100. Buy it and the software (around $60) and you are set to custom make any cut you can imagine!
