I was thinking about getting a head for the monopod, but I thought about it for a few minutes and decided that I probably wouldn't need it. The only thing the monopod is good for is to stabalize normal, horizontal photos. If I need to take a picture of something that's closer to the ground or higher up above, then I can just lean the monopod a little bit. If it's so severe that I need a head on the monopod, then I'll just use my tripod or shoot hand-held. Besides, the only decent heads that I found for it cost about twice as much as the monopod.
And in reality, the thing I'm worried about most now is the viewfinder. I need to find some sort of extender that will help keep my nose from smudging up the LCD. I'm not sure how the one I linked to above will work, so I need some advice before I go buying anything else. I'm not sure how well that one will serve my purpose, but so far, it's the only one I've found.
And about the IS. I haven't had much chance to play with this lens yet, but from the little bit I've use it so far, it seems to work decently well. When I get some more free time, I'll post some pictures.
Ty. It took me quite a while to decide on that lens. Out of all the choices I had, this one had the features and specs that I needed and was within my budget. The monopod was a simpler choice. I was looking at a few Bogen/Manfrotto monopods, but they wanted quite a lot more for a product that does exactly the same thing as the Slik that I bought. In fact, the one I bought is quite a bit lighter than almost all of the Bogen/Manfrottos that I looked at. This one matches my tripod, too.
