I am on the lookout for a decent laser measure. I do a lot of surveying work and could really do with one of these.

I use a Bosch DLE 150 at work and it is very, very good, but a bit pricey at £250, so really looking for a recommendation for one of the cheaper ones. Plenty on Ebay, but then again i have used a few cheap ones that are very inaccurate, hence need a recommendation.

Must have pythagoras function.

Thanks.
