I needed one of these and found that the retail price was much cheaper when buying directly from Huepar than Amazon or other brands. The bonus was that it shipped from their US warehouse too!
Perhaps a niche product, but some Ozbargainers may be cheap but insist on hanging all their pictures perfectly aligned and level. You never know.
Note that shipping from their US warehouse is purely due to inventory, which I have no idea about. Mine shipped from New Jersey.
Check out the Huepar website for all the details, but the 603CG is pretty powerful (up to 33ft range), 360 degree range for the lasers, and also has a pulse mode, so you might also want to pick up a receiver now or later for outdoor work, like a deck, concrete slab, or fence that requires long distance leveling.
Pretty decent reviews from what I've seen.
This is my product display picture, I also allow huepar to serve as advertising
