If you want a red laser (which I assume you want since you posted in the "Red lasers" forum) a LPC-826 would be your best choice. It costs around $10, At that current you should get around 300mW, which is enough to light matches, pop balloons, etc..... the LPC-826 is 660nm which is the more common red, if you want a more orange red and more power than you can get a Mits. 638nm diode but that means more $$$.
