Where do you buy hang gliders from?

I'd like to get into foot launched hang gliding, specifically the jet powered hang gliders interest me ( https://www.youtube.com/watch?v=JfWvsqumK48 ), but I have no idea where I'd start.
Preferably something midrange, pretty good performance, at a pretty good price. Cheap and forgiving to a beginning hang gliding pilot.
Not interested in training or training schools (probably the closest to me would be HG community around Stone Mountain, GA) or the proselytizing thereof, so... you can save your breath and skip that. Just show me where the best places are to buy bargain basement good equipment from. (Something of an answer a little more specific than "the internet").
I may pick up another VJ-24, the glider version, as I know where one is, not the "w" motor powered version I already have, but it'd be nice to have something collapsable that would fit on a car roof to play around with. I think the glider VJ-24 would be a good test bed to mount a homebuilt jet engine onto the frame behind the pilot, as it's not weight shift controlled.

My 20ft ultralight trailer build out to haul my VJ-24w and Poorboy Ultralight is nearing completion... finished wiring the lights and bolting the support boards to the floor, have almost nothing more to do than some last torquing and loctiting some bolts to the frame, then chalking some lines and putting my already painted plyboard to the top.
