I played a spider 2 combo and it was so-so.I played the vetta 2 combo and was supremley dissapointed.I have no idea how well it works for direct recording,but have heard good things.
You really can't fake tube sound/response so they dont do what some people(me included)would like them too.However...if you want an insane amount of sounds/tones then the stuff is great.
If you need a bigger amp,then get a decent mid to high range priced head and cab(like a marshall,peavey,mesa e.c.t.)Or you could get a power amp for your pod and hook up to a cab.
Try once,fail twice...
