Best amp for a resonator guitar?

[frank1985]

I recently purchased the Classic Cantabile RS-1 Resonator guitar (no pickup), and am now looking to purchase an amp with a decent clean sound. My budgets is around £200. Any recommendations?

Thanks in advance.

EDIT: A slightly unrelated question; can I get away with using a thick string guage (062 on the bottom), or will it 'choke out' the single cone? Maybe medium guage would be better...?

No pickup? If there's no pickup at all an amp isn't going to do you much good.

A quick google for the item suggests it comes with an on-board piezo - the kind of pickups that come with electro-acoustic type guitars. A friend of mine uses a Marshall acoustic amp and I quite like the tone, but personally I usually prefer to put electro=acoustics straight through the PA.
