Guys, i need a application to use for my MSN account, so basically it works like any IM program...Which one would you recommend?

I've browse through the Itunes store, and this two application caught my eyes

1. Nimbuzz- Msn messenger plus skype account with free chatting
2. Beejive - Famous messenger but it cost USD 15.99 to download it (Does it worth the price?)

Can any experts here show me some guidelines?

Thanks heaps guys, personally i tried Nimbuzz just now, always got disconnect, so it ain't good for me. Using palringo as refer, it was quite good so far, anyway, i'll give fring a try.

Thanks for all the advice guys!
