Purchased my first ever laser from Hong Kong the other week... and boy am I impressed!!
Firstly, I should provide a link to the provider...

I purchased the small laser unit which is currently averaging around £25-£30 pounds called Aura Lighting.
At first I thought.... wont last, but worth a shot! And true to form, the light arrived, and after plugging it in, the RED laser diode blew.
Contacted the supplier and within 4 days I had a replacement diode (repair was VERY VERY easy... simply plug and play)
--- so for starters
GREAT CUSTOMER SERVICE!
Anyway... the light unit itself is fairly small and comes with a nice tripod stand incase you don't want to mount it to your rig.... Use of it is very easy, and the speed of the laser clusters can be adjusted according to what you need.
The coverage of the light is OUTSTANDING! I kid you not, I was easily able to cover a 25ft x 25ft square... and could cover more if needed.
Personally I think two would be plenty for a large function.
The company also offer other laser types... and if they are of the same build of the Aura Light.... WELL WORTH THE MONEY!!!
I'll post some pictures and videos shortly.
