red laser pointers for presentations

Hi all,

I have managed to break both my red laser pointers in my dome , mind you
they were getting on a bit.

Can anyone point me in the direction of a decent UK supplier? I got one from
eBay but it gave an elongated red line not a dot!. and only lasted 5 days
before it packed in.

Any ideas and suppliers greatly received as I need to get a couple ASAP, I
am working next Friday and need one by then at least.

thanks in advance

Andy
