I've used the Hangar 9 stuff you've posted the link to, as well as the DuBro units and I'll post a link of those at Tower.

I like the actual connection of the Hangar 9 stuff a little better, but they are short and require special attention to getting the pivot point lined up with the hinge line. Usually you drill through the surface at an angle; i.e. 90 degrees to the top surface which leaves a bigger angle to deal with on the bottom.

The DuBro stuff is longer and can actually be trimmed to length and re-drilled where you want the hole, so drilling through perpendicular to the chord line can be done.

I've not used the Rocket City stuff since I'm new to this GS stuff, but I suspect I'll be looking at it somewhere down the line since I see so many references to it on these forums.
