i can't comment on that laser level because i havent used one but i did speak to that company last year and they are really helpful.
i have got a pls180 and a dewalt dw087k and they are very good. both have something that the other doesnt and they seem to be the choice of most tradesman so you know they have a track record too! its difficult t pick up a quality laser level for under £100, ie the laser is dull or they tend to lose accuracy when they go around walls.
dave from tradetiler sent me the laserliner out to try last year and this was another excellent laser. the floor square is good value its price.
i agree with diamond tiling, that the tripod is a it of a pain as its only good to a certain height too. i gave got the laser pole from tradetiler which is identical to the dewalt one. they are really handy! You could use an 'easy prop' for a cheaper option but they can be a pain when you only want to lower/higher the laser a couple of mil and you have to faff abount realigning whereas the poles have an easy slide adjust system.
good luck with your choice........
