That page really needs updating! The technology has really been moving ahead, and chips like the A4988 offer current control, much higher torque (with higher voltage motor power supplies) than L298-based drivers, as well as microstepping with just two control pins. I'm very happy with the Pololu boards that I've been using, however they are limited to about 1.5 amps/winding without extra cooling. I'm hoping that Pololu comes out with higher current models soon. See http://www.pololu.com/catalog/product/2133
These not a one-for-one replacements for the L298, but the code needed to drive the board is simpler.
