Advice: which laser level 2 buy?

[John5550]

Hi All,
I'm on the hunt for a good laser level and would love to get some first hand accounts. I'm leaning towards the laser level (indoor? or outdoor?). Use will of course be a brownstone renovation. Any other "must have" tool advice welcome!
Thanks, and happy leveling.
