I'm considering getting the G12 to upgrade my current G9, too bad I have the underwater housing for it as well, might sell them, any interests?

as for the under water lighting, man, there are tons if DIY solutions including a 4" PVC tube with LED lights and a small drilled hole to wire an on-off switch and also with transparent Plexiglass for the lids, take a look and save yourself a bundle of money
