I think ggotch gave you the best answer. He has experience with the product you're asking about.
Buy it and waste your $, time and effort.
I'm in the same boat as you. I want the guardian but I already blew the budget on other essential stuff.
My plan: Just get by with the pens for now and save up hear and there for the guardian.
Buying anything but the guardian is like throwing $ down the drain.
I don't know anything... And I can prove it!
