Motor Ratings (at 7.2 VDC):
No-load Current: 0.27 A @ 310 RPM
Stall Current: 4.8 A
Max Torque: 4.6 lb-inch (5.3 kg-cm)

I'm searching for a simple dual H-Bridge motor driver that would work perfectly with these motors, I've been searching for a week and couldn't find any to be simple and fit the 4.8A stall. I usually use the SN7****, but can't here.

Can anyone throw a suggestion or advice?

http://www.pololu.com/catalog/product/1213 looks promising - 5A peak, 2.5A continuous, dual H-bridge

I looked at those first but I thought D1 and D2 disable inputs and other stuff looked a little complicated(status flag and slew), I was looking for a straight forward motor driver.

lots of affordable h-bridges on ebay like below.
