Does anyone here have any experience with Boaphile Plastics or Reptile Basics( http://www.boaphileplastics.com http://www.reptilebasics.com )

I am interested in getting a 2x4 black cage and I really cannot decide which one I would like to go with. I will eventually be stacking several on top of each other so I would like a sturdy cage.

If anyone can tell me plusses and minuses to either cage it would be greatly appreciated.
