Help with Micro/Mini Gearhead motors for tiny bot

Currently I'm trying to source some decent tiny gearhead motors for under $12 dollars. Today I've come across these:

Also there are some 3V gearmotors of the same dimensions with varying RPMs (from 30 to 100rpm) available as well. The torque ratios are not given for those, however.
