All of you are R Tards. I'm assuming you want a combo amp that will help you get a good COB sound. First of all, a line 6 150w digital amp is a huge waste of money. That's about $500 for a compressed sound and you'll never in your life need all that volume. Furthermore, if you decide to play with a drummer you'll have a hard time cutting into the mix with a digital amp. The Peavey Vypyr is sort of a gimmic amp. It comes with a lot of effects and stuff like that but you're gonna miss out on some tone. And that's a $650 dollar amp. I have two suggestions for a combo amp for you.
Peavey 6505+ 112 combo (

This thing is all tube, and it's a balls to the walls metal amp. It has all the gain you'll ever need, and you'll get more of their current tone out of that amp. It's 60w, but since it's tube it's actually louder than the 150w line 6 digital.
Bugera 6262 212 combo (

This amp is essentially the same thing by a different company. From what I've heard it has more low end, and it could potentially sound thicker due to their being two speakers in the cab.
These amps don't have all of the presets and effects of the amps you originally posted, but you can land on a much much better tone with one of those. Just make sure you boost your base and mids if you want to get an Alexi type tone.
