I don't think you want a monopod. You'd have to hold onto the camera all the time.
There are number tripods that could work. You best bet would be to go into B&H and look at them if you are in New York.
Bogen makes a couple of nice ones with small fluid heads (up to about 8 lbs.) that are in the $200 range I've seen. Bogen has the 701 head coming out in the next couple of weeks or so. Bogen has a lightweight carbon fiber tripod with fluid head that is between about $250 I believe.
Here's one, but there may be better:

Also, you should look at Velbon. For around a hundred dollars you can get a dependable tripod and fluid head that should suit your needs:

There are some nice little tripods if you don't need a good head. If you can go to a huge camera store and look, that would be best, at least to give you an idea of what there is.
