Presentation clickers

[HairyMaclary]

After a presentation today where I spent the whole time hunched over the mouse I need to buy a presentation clicker. Ideally one that can work on multiple computers so no complicated set up needed. Ideally with a laser pointer too. Any ideas?

I've a Spotlight Remote Wireless Presenter from Logitech. Battery lasts forever and is rechargeable. Range is huge (I've literally walked around a huge auditorium presenting and it still works). No idea how much they are, though, mine was inherited from a departing colleague.

They do look good, but are £115! I don't do enough presentations to justify that at the moment! Thanks though.

I bought a £10 one from amazon and it does the job fine.

They should just plug in with a usb like a mouse. I used to have one. Think it was Logitech but I didn't spend anywhere near that!
