I've looked into th=

motors...with gears and all it'll run you about $120 A MOTOR for a sma=
ll =

walker.  The motor is just a hair smaller than the BG Micro Lens =

motors, but is more efficient.  Trust me it's easier to get that =

for $30 deal for the BG Micro's, unless your really into =

If you're still int=

can check out their website...it has PDF's on all the stuff they =
