Invest the money in a better amp. The POD sucks too much tone, and won't make a difference for you anyway.

MAte i've got one, and with the optional metal shop upgrade, through a 65w marshall valvestate, its sounds pretty bloody good...

Theres threads all over the place if you want reviews, but i personally swear by them

If you are checking modelers out, make sure to check out the Boss GT-8 and the Vox Tonelab SE. I think that they both beat the POD out for modeling. I didn't like any of the POD modeling when I owned it. It all seemed lifeless, fuzzy and thin. The Vox and Boss are a little more money, but you will probably be more satisfied with it.
