I didn't like my crank Go! at first. There was a learning curve to it. Now I lust after the electric Go! In my opinion, it's really worth the initial investment. As I grow older, I become more and more interested in equipment and approaches that (1) save me time, and (2) save my body from repetitive stress.
If you make quilts and you can afford it, get the electric one and *just* the dies that you are using in your current quilt. If you end up really not liking it, you can recoup a large part of the investment by re-selling it.
My preference is for the electric Go! Every single post I have seen from users who had a hand crank Go! and decided to try the electric absolutely loves the electric. The Studio is great for some people. However, it is most useful if you have a dedicated space where you can leave it up. The current version folds to take up less space; however, it is still quite heavy to move around.
