mmm, Maybe you should also consider asking youself this....
is it really necesary to buy something new???
from your signature I can see that you are working on a lot of things, I wonder why would you like more???
As stated before, try doing some research in those things you like, also you must ask yourselve if that trick that you are lookng, can adapt to your performance style, or necessities....
Take exile for an example... it looked like a great "must have" effect, but it really doesn't goes with my presentation and the kind of guy that I am, so I instead bought "the paper engine" and boy, I am sure happy with it.
just my thoughts, cheers!
