Thanks, Neil. I got some lights at Lowes that are pretty much the same as the ones he uses (for a lot cheaper), and plan on using the nut/bolt method to avoid sharp points. I guess my main concern was putting in the cord grommets. For those, you have to use a large drill bit, and I guess I'm just nervous about putting that big hole in the cage side. I don't want to crack or warp the plastic. Guess I'm just paranoid.

And I also emailed Rich about it, so I can see what he says as well.
