I agree with you Flake. My point was you implied (or, at least, thats how I read it) that the OP would, if and when they upgrade, go FF. This isn't necessarily the case.

Absolutely. I completely agree. The lower distortion is partly due to the fact that it's not quite so wide but it is also a better corrected lens.
It's also a question of budget. Personally (and this is my own opinion - it's not based on lab tests etc.) I think the 10-20mm is the best value for money. I'm not sure I'd buy the f/3.5 model as it's quite a but more expensive than the f/4-5.6 (£390 vs £520 at WEx).
