FWIW, if any of you lot out there in YD-land want to get into U/W videography on the (relatively) cheap, I have an excellent housing going for v. sensible money. Only downside is, it's a bespoke Amphibico 100m rated job that'll only work with the Canon MV-1 (or Optura 1 Stateside). Reason being I flooded it a couple of years ago, long story, entirely my fault and couldn't get a replacement as Canon don't do 'em any more (so got a lovely new Sony PC6 and rather less lovely Amphibico housing on the insurance).
So if you fancy taking a chance on eBay with an MV1 (if you can find one) or an Optura1, then give me a shout.
PS I DEMAND AN APOLOGY from all those anal 'stills' types out there. Enny Fule No that video brings out so much more of the dive experience than bits of paper/JPEGs can
