Laser alignment

Can anyone recommend a place that sells a laser designed for bikes used to align the wheels.

Cheers.

The guy that does my bikes uses a normal laser pointer pen that you would use at work. It works a treat

Woolworths currently have laser levels on offer for £10 … they have a nice flat side that can be placed against the tyre on each side of your back wheel … I got one specifically for this job and it works a treat!!
