Yeah, that's my preference too.  I don't think I want to spend another
chunk of money on motors before I'm sure those are the ones we want.

Side note:  I predict a spending of about $200-$300 on our robot.
Actually, the -$300 was cause I'm not sure how much the chips and
everything cost and the amount of batteries we actually need.  =P

The serious shaft work is also what I'm afraid of at the other end of the
spectrum.  How much gearing would be required?

The Lexan base is approximately 3 lbs.

Most AA batteries are about 22 to 23 grams.  So, say 230 grams.
