The Laney VC15 is mint, that would be your best choice considering it is actually in budget (minor dig at the double budget recommendations!). Everybody raves about the TT (and I've got my eye on the new combo) but with the head and cab it's no way near as portable as the VC15 and does not have reverb, so either budget minimum £50 for a pedal (Holy Grail) or don't bother playing Albatross!!
You could go the modeling route, Line 6 and Vox DA5 etc, that is basically digitally produced models of famous amps in a solid state format, this will give you a good range of sounds but can sometimes lack a little warmth and articulation that valve amps deliver.
Here's a summary of smaller amps I've owned.
Fender Vibro Champ
Very versatile, okay Digital effects with a valve power stage. Fender blackface(ish) tones in a small package. good at low volume.
In action

One trick pony, sounds good at 3/4 volume but not loud enough for a band, too loud for home.
Laney VC15
Had one, sold it, wish I hadn't. Warm sweet volumes at bedroom levels and sounds great cranked.
Gibson Goldtone GA-15R
No longer in production. Lovely cleans, great harmonic rich overdrive and rich reverb, lovely sounding amp. Valve bases melt, crackles like a bitch and gets sent back 10 times, postage at my cost. Stay clear
Fender champ 12
No longer in production but readily available. Good fender clean tones although clean channel is limp and drive is a bit mushy
Fender champ 600
never owned but tried. Good twang for the bang but speaker farts and no verb.
Orange Tiny Terror combo
I'm going to get one with a Holy Grail Reverb so I can play Albatross!!
