If you're looking for something lighter for packing, I once had a Manfrotto 190cxpro3. Used it with a 65mm scope but I still think it would work fine with an 80mm. Not under $200 for a new one but a used one should come up for that.
The most sturdy tripod I used was a vanguard something or other, but I wouldn't of tried taking that many places. It was under $200 new.
