Cheap place for wrench rails?

Do any of you know where to find wrench rails in this style for a little cheaper than on the Snap On site? There are some on ebay, but they are the tapered style, and I'd prefer the teeth to all be the same size to make them easier to cut to length.

If I don't find any, I can get aluminum T bar in an appropriate size for around $9 for an 8 foot run and cut my own notches in it (bandsaw, I guess).

Thanks.

yeah i think they make it for snap on, the brand is Ernst and i see they have a magnetic version, wouldn't be surprised if snap on comes out with the magnetic version

heres the link to the website
http://www.ernstmfg.com/products_wrenches_rail.php and they are made in the good ol' usa

i have the snapon ones just cuz of the convenience of passing by.
