I also purchased a used AP portable pier like Logan even though I have the PMX "pyramid" (tripod). The AP pier is very light but extremly stable and will be used in my home observatory when I get around to building it. The only drawback I can see with the AP pier is that it is really only suited to flattish ground because the feet don't have adjustable screw pads. I am in the process of machining up an adaptor for the 8" diameter tube which is being made from an 8 1/2 " dia x 1" thick slice of aircraft grade aluminium and a 9" x 9" x 3/4" plate of the same material.
