Not to hijack the thread, but...

The best solution I've found for the 33 holes to hang 11 photos problem is a level with a laser in it. The laser can be adjusted to a spot or a crosshair (for handing pictures, cutting holes for can lights, etc.) I bought a kit at Costco for under $20 US. You can also find them on E-bay. The company's name is "LazerPro". Likely, that's not the real company's name, just the name of the folks that put it in the packaging.

It recently dawned on me that the laser level will be very handy for getting the toe-in of my soon-to-be-ordered Axioms idential.
