Another vote for the Fryette here. I've had one for a few years now and it's absolutely brilliant. Very usable and it has a proper pot on it as opposed to the notched attenuation that some others use. Loads of features too (DI, FX loop, ability to mismatch cabs and you can reamp a small amp to 50W). Also has some additional tone shaping too. I also own a Weber Mass 200 which is also great but the PS-2 is much better. I use it with a 100W Super Lead and a JTM45. If it broke I wouldn't even hesitate about buying another. I can't speak for the Waza TAE or the OX. They both look great too. The extra effects and functions are supposed to be great but they're overkill for my needs. I reckon you won't go wrong with either though. Hope this helps.
