The Blackberry curve 3G smartphone?

I cannot decide whether to get a blackberry curve 3g smartphone. I have to get pay & go phones as it's an easier plan for me, but it's always more expensive. For a pay as you go blackberry curve 3G, it costs £200. I really want one but I don't really want to spend all my money on one. So if I am to get one I want to make sure it's going to be worth every penny. So do any of you have a blackberry? Please can you post your blackberry reviews here? It would be so much more helpful to have other peoples opinions! Thanks, FatalExplosionOfHappy.
