I bought a Toneport a few weeks ago and I love it. Make sure you get the Metal pack addon if you want to record anything high gain though. The amps in there are a cut above the regular ones when it comes to metal (big suprise...). Also, don't expect flawless simulations or that you can tweak the models as you would tweak their real-life counterparts. Just turn the knobs until it sounds good.
you can find both guitar patches, the bass patch, and the kick/snare samples i used right there...the guitars sound pretty lame untill you put both of them in a mix together, then they're decent
