A great aluminum Manfrotto can be had for around $175. The head is the part that the scope attaches to to allow movement of the scope, personal preference there(I despise the pistol grip models too). I use Jim White's head--

For light weight tripod, think carbon, but more $.
Thank you, thank you, thank you. Most pistol grip heads are shit. That's right, I said it. Fucking toys.

Carbon, light, expensive. If you're not hoofing it, go aluminum. If you are up and down the side of a mountain, sure. Otherwise, take the extra money and spend it on the scope. That's what is doing the work.
Most pistol grip set-ups are cheap pot metal, junk. Do you think that I would put a $3k+ spotter on a manfuck-o pistol grip, you are very high.
Try it with an 11 lbs. lens/3 lbs. camera, wouldn't last 1 season.
Buy the best scope that you can. Period.
Buy the best ball head you can afford. Check out Really Right Stuff. Just look at their site. Read a couple of their tutorials. Silky smooth, tight, repeatable.
Choose your tripod accordingly. Truck to bench, you don't need a carbon graphite racing tripod. If you will be carrying it over hill and dale, spend the extra dough.
Think about this: You could be glassing all morning before you take a step. Buy a good scope. Spend $300+ on a good ball head.
Would you: good truck, good rifle, good glass, $10 pocket knife? Cleaning your fingernails, sure. Skinning big hogs, no.
Good Luck.
