I love me Go (Big the electric one) not only cause it helps my shoulder/arm issues but it's so accurate! I help with a beginners class and had cut my samples of FG & HST from the Go and when it came time to demo how to square and trim excess--there wasn't any!
I bought the strip bundle when I got mine--use those strip dies, especially 2.5, 1, 1.5, 2 and 3.5 strips all the time. You can even cut bias binding with the 2.5. I add dies as they go on sale (on the Accuquilt site) and I need them. The Qubes are a good place to start with dies also.
