I have something coming up where I'd really like to be able to shoot underwater if at all possible. This would be in a large pool housing dolphins -- not exactly sure of the depth. The full blown GH2 underwater housings are a little steep at $1400 and up. Something capable of fitting the PM1 with the 20mm or 45mm might be exactly what I need. Does anyone have experience with something like this?

At $20, I'm also nverous that it's a little too cheap. I'm willing to pay more in the 50-100 range without even blinking if it'll do the job, but 1400 is way too far up the scale, and the dedicated PM1 housing is still 600. Any suggestions would be greatly appreciated. I was thinking it might be possible to rent housings, but haven't managed to find anything yet.
