Photoflex Transpac Dual Kit Case vs Alien Bees Location Case

I'll soon be purchasing 3: Alien Bees B800 units (and a 4th one in the future). I need a case to hold these plus various items like reflectors, cables, folded soft boxes, stands, etc. It will be used primarily for storage in my home and local travel; no airline trave.

I have only $200 in my budget for the case.

I like the Photoflex offering but it's not a hard-shelled case. I'm afraid that if I load it to the max and store it upright the weight will eventually cause the case to warp, sag and maybe become unstable. Also, it looks like the wheels will evetually crack under the load. The Alien Bees case won't hold as much, has no wheels but looks far sturdier and more secure.

Suggestions please?

That photoflex case is nice but gets quit heavy fully loaded.
