Where can I get photocells and lasers? Answered

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.

my house and pkt radio shack alot o places my freinds oh and plz add me people who see this same goes to u i need freinds here
