Hey man,
Just in case no one else has said it: If you get a 210 combo, you could always get a fifteen (if that's what you want) later on and put it underneath. That way you should get the full power of the amp and a choice of tone. If you're in the cheap second-hand market, you'll be able to swap small cabs around with very little money loss. That way you can see what suits you when you come to upgrading.
'Though, money and music style is an important factor.
