Hi Ron,

I bought a pair of 16'ers for 1000 bucks last Summer and stood a number of stick built walls. Remember that 16'ers will stand just over an 11' foot wall: 16 X 1.414.

I think for small, shorter, lighter bents you could get away with Walljacks, but for the money, I am convinved they are the right tool for stick framers, but lacking for timberframers.
If you do get walljacks, I can pass on the void-your-warrarentee modification that everyone does for strength, safety, and common sense.

I would suggest any number of options first: site rigged gin pole, crane truck, forklift, etc.

Then there's always a keg of beer, pizza, and all your strong friends...

Best of luck.

Zach
