I am all for free enterprise. Lets show a comparison between the products...Our product and yours.
First the mounts
Brand "O" mount:
A simple spacer that utilizes the plastic bag hanger as a support system. An interesting approach to structural integrity.
Springtail/MPAC Side rack mount
A complex billet mount that bolts directly to the metal body mounts. The rack bolts directly to the billet mount allowing the rack to be removed without disturbing the hard mount.
Any possibility of rotation of the mount is controlled by billet extensions that protrude into the factory body mount.
Securing the base of the rack
Brand "O" method: What appears to be a rubber bumper pad with no actual control of rack movement
Springtail/MPACs method
If the beefy Billet mounts were not enough, we instruct users to bolt the base of the rack through the shelf of the cargo area. This stops any potential movement of the rack by inhibiting any possibility of a fulcrum effect.
The Rack itself
Brand "O" Rack: Flat plate with some holes
Springtail/MPAC Rack
Folded for additional strength and the ability to use the whole grid not just the parts that do not have a mount nearby.
The grid is designed not only to accept almost all MOLLE products but also to lock the straps in place.
We even thought of providing hand access so that the user can remove standard MOLLE bags with out pulling the rack. It is quite unique (which is why we took the time to patent it).
Finish
Brand "O" Finish: bare metal or so it appears
Springtail/MPAC
Again the effort has been made to produce a quality product that will look good for years to come. Our racks are powdercoated in a state of the art facility. Each rack is produced locally and undergoes a very intense inspection process before they are ever released to you.
Testing
Brand "O" testing...not sure, you will have to tell us
Springtail/MPAC
Over the past 5 years our products have been used and tested by...
The military in Iraq and Afghanistan
Fire departments
and Law Enforcement
Under all circumstances, the MPAC system comes back with stunning reviews...not only with the product but also with customer service and quality.
What Brand "O" offers you
I must agree the OP that they do offer a
"cheaper" product.
For an extra charge, they will personalize the rack...of course, the real price is that it will either potentially limit your ability to get to the back of the rack or it will occupy the grid space needed to hang your MOLLE bags.
What Springtail offers you.
Springtail can offer you a proven quality product that is designed by engineers in a state of the art facility, tested by professionals of many walks of life, and will last likely out last your vehicle.
MPAC and MOLLE is all we do, not only do we make the racks but also vehicle specific MOLLE bags and offer several styles of quickfists and mounts.
We even offer discounted packages to make the velue even better.
What appears inexpensive at first probably won't be in the long run especially when it comes to potential safety issues. For less than the cost of an ER copay, you can get the real thing.
Basically...you get what you pay for

version of my concepts...at least you could become a vendor and support the forum.
