First off (and not to be a jerk) you just can't get certain tones at the price range you're talking about. So maybe set your standards a little lower in that department... lets get you heard in the mix

. I'm not sure of the difference in price on your side of the pond but I'm a big fan of 2x10 cabs for small gigs/practice.
I'd check out the Fender Rumble 350 and the GK MB210.
I agree that a DI is great to have but soundmen hate using amp DI's. It's also provided at most clubs here in the states.
