Why not just build your own? I built one that has a powered height adjustment with wireless remote control and it cost me about $70 for the whole thing. I am going to write an Instructable how to do this in a few weeks.

Did the same as Soartech, motorized vertical axis with remote control on a home-built rigger. You should see the envy from the poor guys who have to run to the rigger to adjust the height. I just stand by the fuselage and run the wing up and down until the pin bushings line up. Found the linear actuator on ebay, same for the remote and relais box. Price for the parts is around $180 (not $70) and that's just for the height adjustment.
