Good locking overhead rifle rack for a Jeep Cherokee?

[fizassist]

Howdy folks,
Could anyone recommend a good locking overhead rifle rack that would work on a '95 Jeep Cherokee (no partition, no roll bar)? I'd like something that would be (reasonably) secure against theft while the vehicle is unoccupied but have a discreet unlocking switch. Being able to have a mag (even 20rd) in the gun is a major plus. So far, I've looked online at:

Pro-gard G5040ut (-3?)
Big Sky ELS-270 + UCB (undercover bar) mount
Galls "VP217"

For perhaps understandable reasons, I haven't been able to get much info about these racks from retailers or the manufacturers. Does anybody have experience with these racks, or could you recommend another brand or model? The rifle would most likely be a flattop 16" AR15 with an aimpoint on the receiver. I would prefer somthing that mounts to the side of the headliner instead of bolting through the top of the roof.

Thanks,
fiz
