What is a good laser level that shoots around 90 degree corners?

I'm a complete putz when it comes to the whole home improvement/repair/whatever thing, so any help here is greatly appreciated! I've been looking at the Black and Decker Bullseye, but I've been told and have read that it only goes about 6 inches around a corner, is there anything that goes farther that won't murder my wallet (or at least the meager contents thereof)? What is it called?
