Where can I get photocells and lasers?

I need both types of photocells, ones that start being resistant, and ones that electricty go through. Also, where can I get some lasers that would work with the photocells?

I meant cheaply... Otherwise, my local Shack doesnt hold them. -PKT
radioshack actually has relatively fair prices for photocells, 5 assorted for $3.  Photocells just sense light, a focused laser will just mean it senses more light.
