For the monopod, get whatever you can afford. If you can pay $250 or so, buy a Gitzo 2 or 3 series carbonfiber monopod. Or, you can get a similar product from Gitzo look-alikes Benro or Induro for about $50-100 less.


As for the head, there are two monopod heads that are worth a look:


Manfrotto 234 head - will support everything up to a 70-200.


Really Right Stuff MH-01 head - this thing is the best monopod head out there and is rated to 75lbs.


hope this helps
