Which motor is the best

On my search for a motor which suits for me I found 2 I could use ( remember i'm searching for fast motors not ones with a lot of torque 

motor 1 http://www.gizmoszone.com/shopping/agora.cgi?product=Gearmotor&user4=810series;ppinc=1g note- the first motor with the 2700 rpm.

motor 2 http://www.pololu.com/catalog/product/1093

The problem here is the first motor does not appear to have any compatible wheels or chassis whereas the 2nd motor has many compatible wheels and chassis.

The gizmoszone motors

are plastic geared. The pololu motors are metal geared for $2 more. The gizmoszone motors have squat for torque compared to the pololu drivers. You have already been told torque will be the issue.

Whoops made a mistake I

Whoops made a mistake I thought the gizmosone motor had a stall torque of 15oz inch but it was 15 oz cm
