i call bullshit on that one. buuuuuuuuuuuuuuuuuuull-shit.
if your v-amp can cut it on a demo, so can v-drums...get a decent little rubber kit, export the tracks into a good drum sequencer with a solid sample library, and no one will ever know the difference.
A good drummer, in a good room, with a good kit that's been properly tuned, with good mics, into a good board with a good engineer doing the tracking will outperform a set of V-drums for 99% of situations ten times out of tens (electronica or trippy electronica-influenced stuff, and here I'm thinking Massive Attack, is that one remaining situation).
The reality though, is in most home recording situations you're lucky if you have more than one or two of those. A set of V-drums running into something like Drumkit From Hell with a good set of samples loaded can sound pretty damned good; certainly better than a drum kit in your guitarist's garage with two SM57's as overheads and a third on the kick.
If you've got the ability to do the former, go for it. If not, and if you're not either intentionally chasing or at least prepared to accept the lo-fi vibe a budget drum recoording will give you, then it's certainly worth considering the latter, especially if you have access to a set of V-drums.
FWIW, I personally diisagree that a Vamp is just as good as a real amp, but all the aforementioned caveats apply - the V-amp is certainly a hell of a lot easier to record.
