Not to mention that there are a lot of time zones and not everybody is on your sleep schedule.

But like DT said, there's a lot of people around who are good with PWM'ing 2 motors bidirectionally, which without some sort of method of counting rev's or speed, good luck trying to get the thing to run straight.

The big thing I can suggest... Get yourself 4 LEDs, wire them up in 2 pairs of opposing parallel before getting PIC driven MOSFETs connected to motors.
That way you can play with PWM (no matter what your method, software, hardware, off-chip driven, etc), watching LED brightness, and the opposing parallel pairs of LEDs will give you a visual indication of both direction and relative speed, with practically no chance of blowing up a PIC.
