Looking at the Vox page, the AC 15VR is definitely not a pure valve amp, as it has a solid state power section, and only the preamp is a valve, which leaves the Peavey the only choice given what you want. Another Peavey in a slightly cheaper price range you may wanna check is the Windsor Studio combo, 20 watts, all valve, 249, haven't heard it, but it's meant to be good, at the price, and a good platform for upgrading, worth trying. Have heard good things about the ZT amps, but they are 100% solidstate, if that's important. Ultra portable though.
