Me! I bought it the first week it was available to buy. I was looking into getting the big Studio cutter like the quilt shop has and found out the Go was being made. Much cheaper and easier to store then the Studio. I have most all the dies except the rag quilt, I've use it and it's a hassle. All the other are great. For all gift giving days I ask for new dies. That's how I have most of them. I use the basic die shapes the most and the strip cutter. I really like the Tumbler die. Accucut gives a Go away every Friday on their Facebook page and has lots of info there. Now they have a die coversion chart, to covert most any quilt pattern to fit the dies. I think die cut machines will be just as normal in the next few years as the rotary cutter is now.
I have about 1/4" to 1/2" waste. I don't understand how anyone can have more waste. If you cover the whole die then you will have lots of waste. They do that in demos to save time and I think that gives the wrong impression. It's not going to please everyone but I'm glad it pleases me. :D No more aches from rotary cutting.
