I've got a couple from Skil that were pretty cheap at Lowe's (I don't know if you have them in your area): http://www.lowes.com/...laser&facetInfo=
That link doesn't say anything about a tripod, but when I bought in-store, they even came with crappy tripods. I'm generally not a big fan of Skil tools, but these were cheap and they work fine.
I also have a PLC that I bought through BikeFit that also fits the tripod mount.
It looks like Lowe's has a really good sale on a Bosch laser level going right now:

I don't have experience with this particular unit, but I do like Bosch tools a lot.
