Construction Tools: laser level

Hi all,
I need to pick up a rotating laser laser; as I’m rehabbing an old row-house with some UN-level floor joists. For those that do thier own work: can anyone recommend a brand/type of rotating laser level? There’s a huge selection of them on the market, from thirty bucks to over a thousand!! Yikes!

Thanks,
dan

I got a craftsman brand level given to me for Christmas a couple years ago. It works just fine and I’m sure it wasn’t terribly expensive.

thanks Justin,
i’ll check it out…
