Good beginner skateboard?

I'm looking into starting skateboarding. I'm not gonna want to do many tricks or anything, at least not for a long time, so I dont need a particularly brilliant board, but not sumthing that'll fall apart if i go over a pebble. If anyone has any advice on what kinda board i should get i'd be grateful. Am I better off getting a complete board or a seperate deck and wheels n trucks etc? Thanks!
