"I think a roland micro cube is fine for this sort of situation"
I'm kind of out of date, but these were ace last time I was looking, very nearly got one myself. If you just want a cheap practice amp, I've got a wee BC Rich one stuck in the cupboard which I've never used, it's not very good frankly- it's the sort of amp you get along with starter packs, very basic- but it makes noise and you could have it for, oh, probably £20 would cover it though I'd need to check it actually works. I'll never use it so it'd be nice for someone to.
If the budget allows something a bit better would make sense though, ideally with some FX built in as that's a big money saver if they're half decent- frinstance when i bought my Vox, I funded it by selling a whole load of footpedals, since i just didn't need them any more with this amp.
The Mini Strat looks like a pretty good idea, but is he used to full sized guitars? Generally speaking the correct answer for a first guitar is "A Pacifica whose model number doesn't start with a 0", they're very hard to beat but a lot of the Squiers are now very good value too.
