Dido to everything that was already said!
I'm a bit confused....why do you never pay full price for anything over $20 ?

If you can't afford it then I'd say save your pennies for as long as required and eventually you'll have an excellent piece of software which is worth every cent (And then some!). If however you can afford it, but you just have some sort of issue with the figure '20'....well your missing out, because it really is excellent software, and well worth the price.

Good luck whatever you decide.
