My first rule of phones is do not buy a blackberry. My second rule of phones is DO NOT BUY A BLACKBERRY! These days BBs are strictly for teenagers and American business men. And with all the cheap, reasonably spec'ed, Android device being released recently I don't think they'll hang on to the teenager market much longer.
Apparently the latest BB OS is noticeably better than the old one but still no where near IOS and Android in terms of usability and it's kind of a one off since the next generation of BBs with have a QNX based OS which will be entirely different. Email and messaging seems to be the only thing BBs do tolerably well, except when they don't do them at all. (E.g most of this week)
I think, now, WiFi is sufficiently available to replace roaming for most people, if not get a local pay as you go data only sim (The iPad has had at least one positive affect) and you're good to go.
With that budget Lunar, I'd go for a Galaxy S II (Or actually I'd halve my budget and then get one but I live in a country with slightly less abusive telcos so YMMV).
