LED Shoppe green laser show modding

I just received the $12 "10mW" green laser show thing from LED Shoppe, it's pretty cool. I've already taken out the diffraction screen thing, and turned the pot down. But before I play with it more, I'd like to know what resistance I should set it to. I think it was at 880 Ohms when I got it... how far do you guys turn it down?

Cool picture of my new laser for incentive?

Some more pictures.
