Multi Colored Laser Pointer

Hi I'm looking for a multi colored laser pointer that shoots out different colors on the same device. Preferably, under 5 mw and includes green and red for under 50 bucks. I'm not sure if my budget is too little but whatever help me find one if possible please.

DealExtreme: $31.07 2-in-1 Hybrid 5mW Red + 5mW Green Laser (Supports Dual Laser Mode)

You can use a different battery in it (I think) the answer's here somewhere
