I got the two for my Dad from ReefExotic, they were the cheapest I could find, but I'll be honest I'm a little disappointed in the craftmanship of the LAIII reflectors... I mean I honestly feel I could build my own and have it come out just as nice... It just wouldn't have the mogel mount (unless it can be purchased seperately). Everything is put together with pop-rivets; hell I have pop rivets, how tough can polishing aluminum sheet be? Can't imagine it being tougher than polishing acrylic! I guess it comes down to is it worth the extra time working to save a few bucks?
My 2 cents.
