O2 Vs 3 Vs Meteor. (Advice)

[Shirley Joy]

Hi ladies and gents, (its not a drunken shameful post tonight)
Hahaha, I was just wondering has any of the users of this site signed up to one of the above three's broadband dongle, I'm actually contemplating buying one tomorrow, but I actually don't know which one to get, price is not an issue, but its actually speed, and reliability, I need coverage near enough everywhere I go, that means in about 9 months time I don't want to be bringing it back to them and just to say its not working.
I'm not looking to download, its just really the access to the net I need and I need it to be fast.
Feedback is much appreciated, even drop me a pm and I will be greatful.

Thanks.
T_T.
