I think you need to keep things in perspective in here. The pros here are right, there is no comparison between amp modelers and true high end tube amps. BUT, (and this is a big but), I think you have to get into the $800-$1,000 range of amps before you can really say that the amps sound better than a modeler. Comparing a properly setup V-AMP or POD vs. a marshall valvestate, solid state crate or peavey, lord forbid a rogue or other assorted low end budget amps - sorry fellas I would go with the modeler every time. I challenge you pros out there to argue that !
Most of the people that say they hate modelers have never learned how to use them properly. I hear all the time about people using modelers like effects pedals through their amps (they aren't) , and complaining about the sound. Amp modelers SIMULATE amps. That would be like micing an amp, and then outputting the mic'd amp sound out of your amp. SHITOLA, is what comes out. Amp modelers are meant to be used live, direct to the P.A. (or some other FULL range speaker\amplification setup) or recorded direct. NOT used like an effect pedal. yea, you can turn off the pre-amp and cab models, but that is the whole strength of these things. Used live, direct through a P.A, 99.9% of your audience will never know that you weren't using a real amp, and the .1 percent would have to be a guitarist or recording engineer. Yea, I know direct guitar always sounds like crap through a D.I. - but believe me folks that has changed.
For now I am still using a 1/2 stack tube amp for gigs and recording and an 80's solid state for practice, but I appreciate a couple of the roles that modelers excel at in recording and playing live: a nice tool for recording demo quality quitar tracks, and a small portable back-up for your main live amp rig. In those roles a modeler can really come in handy.

P.S.
I keep hearing POD this and POD that, personally I feel that for metal guitarists the V-AMP 2 has better and heavier guitar tones. The POD has some nice Satriani-esque leads and some decent medium gain crunch, but the V-AMP has better cleans and low end mega gain metal distortion.
