I've got three from them. First one I bought was the High Country. Pretty much garbage, don't even bother. Barely steady enough for binos, and it's a bit of personal preference because I prefer pan heads, but I hate the ball head.
I also have the summit SS-p. Fantastic lightweight tripod, it's the one I keep I my pack. Great for binos and a 50mm razor spotter, would probably be good for a 65mm scope, but the 80 class ones might be a bit much. It's pretty much a sitting height tripod, which is fine by me. The pan head is decent, nothing spectacular but worth the weight savings over something heavier but smoother.
Last is the Pro GT. Came free with the aforementioned 50mm razor spotting scope. It's big, and heavy, but sturdy. I'll probably never use it, I wouldn't want to carry it in the woods. The pan head is pretty nice, smoother than the one on the Summit, but bigger and heavier, so I won't bother swapping it out.
I'm super happy with the summit ss-p and would definitely recommend going with that one.
