I've been thinking whether I should get a turntable or not

I keep thinking what would I be gaining? then on the other hand I am pretty sure that vinyl CAN sound somewhat more refined than CD

I definitely don't want to spend too much on it if I do go down that route, but would I gain much having a simple/inexpensive set up? or would I need to spend lots to get a decent sound against CD?

Thanks for any help and guidance; I really am a turntable virgin, I pretty much know nothing about the beasts
