Have you thought about a direct unit? I get pretty good tone from my Headrush Gigboard, and I know several people like the Helix Stomp. As far as an actual amp, I found a good deal on a Mesa Transatlantic that has a decent Fender tone, and it's very small head. You could pair it with whatever cabinet you liked. I also liked my Ibanez TS series. It had pretty nice cleans. Not exactly Fender, but definitely not Vox. Best part, it was dirt cheap used.
