If you are, "a bit of a preset guy," and you do not mind hardware.. I've got two really great choices for you.
( btw, if you like to tweak settings, "even a little bit," than these two choices go up a level from great to, "amazing." )
The only reason I am mentioning hardware is: "There is definitely less latency. and you already have all the sims, as far as I can tell.
#1:
http://www.digitech.com/en-US/products/gsp1101 This is so on my list to purchase in 2013. I saw it during xmas for $345.. I should've sprung for it. But I was busy buying other things. The street price right now is, "close to $450."
Failing the digitech because you either, "do not want a rack, or its a bit expensive."
#2:
http://www.zoom.co.jp/products/g5 There is also a Boss GT100, ( or 1000?? ) but I'm not linking it cause, "I simply have not checked it out in person yet."
Finally, "I saw the floorboard pod hd500 @ guitarcenter a few weeks ago." I checked em out and everything.. "I was less than impressed."
Really, "The digitech or the zoom, or the ones I think would compliment the already huge amp sims available on the vst/plugin/in the box spec."
