manfrotto 681 (black or silver, doesnt matter).
i have it, love it, does the job, and heavy duty, and most important of all, not overpriced.
edit again: you want something thats reliable; so dont get a cheap one.
edit: you need some kind of head (or maybe you dont, depends how you like it). you attach that head to the monopod (or tripod) and maneuver the head for position / angle adjustment. There's some type of plate included with heads. You dont need a head for monopods, since, you can move it in any direction anyway! 
if you want it to tilt - then manfrotto 234RC - simple and does the job.
(btw i have all the stuff i said in this post)
