Heavy duty tripod

I have my first GEM being made by John Davis and I need a tripod for it.
The mount weighs 30 lbs and has a 40 lbs capacity, counterweights 20 lbs and
the current scope for it will be a 1278. So, we have 67 lbs of stuff.

I found this:

The wooden surveyors tripod.

Also checked out Al's astro and Astronomics offerings.

Also looked at Burlebach's from Germany.

I'd like to keep it under $200. The mount is a tank so I'd like a threesome
to go under it that can keep up with the mount. I may end up putting my dob
on it some day as well (10" XT10, 35 lbs).

So, here's what I'm thinking. Get a shorter tripod (please recommend one)
and put a mini pier on it (recommendations welcome). That will give me a
short tripod for the dob and a taller one (with the mini pier) for the
refractor. Any recommendations for min and max height?

Thanks,

Tom
