Loads of laser levels on eBay, some go for silly (high) prices,
some look reasonable until you see how much they want for
postage. Maybe the odd bargian to be had if you're patient and
can be bothered.

Somewhere in the UK there is obviously a footie pitch-sized
warehouse packed to the roof with Far Eastern lasers, @ something
like £1 each if you buy a crateload. http://tinyurl.com/tdf6

Seriously though, where DO these traders buy the stuff from?
