So I would like to start looking for a good tripod and head to take on day hikes as well as 2-3 overnight hikes with me. I don't want to spend the $300 for a carbon fiber either, so I'm hoping I can find a decent aluminum one for about $100 to $150? Also, as far as the manfrotto heads are concerned, which do people prefer?

I've got a Canon XSi and a 70-200mm f/4L lens (plan on getting the 2.8 eventually) that I am going to be packing hiking with me. The grip head sounds pretty nice, but not sure which one people prefer. I won't be looking for birds in flight or anything... at least not much, that's not my thing. So this will mainly be used for landscapes and such, with some HDR photots. Thanks!
