Three items in bad need

Hi, there,

I would like to buy a laser pointer keychain which can emit the brilliant and powerful burning laser that could guide me unlock the door in the dark. I want to wholesale form a relatively online discount cheap electronics store.

Besides, I also need a high power laser pointer for astronomy watching. Also, it should be a cheap red laser pointer. As matter of fact, my budget only allows me to purchase cheap laser pointer.

In addition to them, a 150mw laser pointer is still required for the coming speech.

Who can tell me something valuable information? Thanks a lot!
