I think i've actually SOLD my Schecter (pending deal) and I've been looking at three amps as a "backup" amp, but also as something that would blend well with my Mesa for recording. I have my Mesa set with a lot of lows and mids, a bit of a darker tone, so I want the "other" amp to be a brighter amp. Now, I know ALL three of these amps fit that description.
Specific amps i'm looking at:
Orange Tiny Terror
Jet City JCA20H
^ List is from top to bottom what i'm feeling about the amp tones, right now the Orange is winning, but the problem is if I go with say the JCA or possibly the Windsor I could probably afford to also get an extra cab.
I am really digging the Orange tone and I think that would set well in the mix with my Mesa as well as giving more of a southern/classic rock meets modern rock tone (Mesa + Orange) which is exactly what i'm going for.
Jet City is a straight up marshal sound so it will blend pretty well but it doesnt get terribly heavy without a boost. Plus the two channel version should be out soon which will kill anything else on your list
