How bout vox ad15vt. could be slightly more for a new one. 2nd hand one is definately cheaper. They have the newer series now which have 11 more amps model. You can get quite alot of different tones out of them. I saw someone selling a black heart tube combo at 230 in the buy/sell section, its quite quite worth it.
But just a thought, I think you will do better with any other stand alone clean amps or one with clean and overdrive channel, as you will probably get effects soon. Some cheap ones like danelectro coolcat OD and stuff is not that bad
