I really don't know what to get, and i need one because my band has 50 watt and over amps. The Ashdown Fallen Angel has been the only one recommended without needing a stomp box, but it's more expensive than i would like it to be.
are your bands' amps solid state? if they are, the ashdown SHOULD be loud enough ( i say should, because I don't want to say for definite, just in case I'm wrong).
but the difference in volume cause by 10 watts will be negligible. Seriously, it's not a linear thing. Google it if you want. you normally need 10 times the wattage (roughly, and with everything else being equal) to get double the volume.
also, i've seen the ashdown 40 combo advertised for about £330, which is only about £30 over your budget.
