110 volt 3 amp dc motor control with basic stamp?

I realize that there will be 100v MOSFETs involved but can the bs2 be used to control the speed of a 110v dc motor? If so, does anyone have one up and running? Schematics? Advice?

PS- does anyone else think the search feature of this forum is crappy?

    I run 90vdc motors with mine, but in reality I am using the stamp to control a 110vac in 90vdc out motor controller. Motor controllers are relatively inexpensive, probably well under $100 for a .5hp motor, which would handle 3 amps. Yes, you can do it with PWM on the stamp, but imo you are better off using a motor controller and controlling it with low level stamp inputs.
