Has anyone ever used any of these pedals?



They have a deal at gc where if I buy $50 of hal leonard books/dvd's i get one of these for free. Does anyone know if they are any good, and what would be the best one to get? the stuff i would use the pedal for would be similar to breaking benjamin, a7x, bullet for my valentine, iron maiden, and metallica.
I bought the stereo chorus on a whim, and I like it a lot. I don't know about the dirt boxes though.

How do you say "I'm okay" to an answering machine?

I have the digital delay, and it's pretty decent. The battery cover broke, though.
