Hey Svart,
On the budget side there is the Epi Junior, Fender Champion 600, Gretsch Electromatic... all stem from the Fender Champ era and the circuits are near identical and make for easy modding. I own a modded Fender Champion 600, which is a essentially a 'Black Face' Champ with fixed tone stack... I modded mine to to match the classic 5F1, removing the tone stack and adding more juice, swapped out the valves with some JJ Tesla's, new Jensen Speaker, all under $300.
The only gripe is the small 6" speaker, great for some 'indie' sounds not the most usable but the amp will drive a 12" cab and I run it into my 67' Fender 2x12 cab for some great high gain tones.
The Orange Tiny Terror is fun as well, but just a head, not sure if you need a combo or not?
You could prob build a nice Fender Champ/Princeton clone with GREAT parts if you were not worried about the looks and drive a 1x12 cabinet.
Cheers
Matt
