Although I've not had the real chance to use my GLL 250, I've tried it at home and more than pleased. I agree the GLL 380 is better, I couldn't justify the cost. I think a plumb level ability is quite useful (which the 250 hasn't got), there's a Bosch GLC 25 which has that feature, sort of between the 250 & 380, but again more money. Guess I just get use to using the 250, but I'm well pleased with it.
