Does anyone here own a banjo?

My 18th birthday is soon and i am looking to broaden the list of instruments i can play.

And i always thought banjo sounded cool so i was thinking of getting one.

Does anyone know anything about them.

I was looking at some on ebay and i am thinking of getting a 6 string - so i can play songs on guitar on it.

or a bass banjo.

Can anyone shed any light on the banjo.

Would be much appreciated.
