opinions on the Mobile Laptop package from Zagros Robotics ?

I'm thinking of purchasing the Mobile Laptop package from Zagros Robotics,
plus an extra motor and motor controller (that plugs into the MC11
backplane). My 'bot mostly will need to drive around the house and
peridoically operate a lead-screw mechanism to raise a platform - carrying
no more than 10 lbs of cargo, I think.

I don't really need to use the Lexan/Plexiglass platforms, but it still
seems like the cheapest way to get a great bunch of motor/controller goodies
even if I don't use the platforms. I'll be using a mini-book PC for the "big
brains" of the bot, and it seems like a great idea to offload to the MC11
unit all of the driving functions, emergency stop, etc.

One thing I would like to be able to do is to upgrade to more powerful
motors one day while keeping the motor driver electronics.

Does anybody have any opinions on the kit ? Other suggestions ?

Also, I would like to see more data than is present on the site for item #
ME2435
    Max 96/99/97 motor 25 rpm, 20 in-lb
    12vdc, 20in-lb torque, 25 rpm motor

If anyone has any more info I would appreciate it !

Thanks in advance!
