DVX UW Housing/Splashbag rental in SF Area?

[Mister Big]

There's a chance I may need a splashbag or UW housing for my DVX during a demo shoot next week. It's only getting dunked a few feet deep in an above-ground pool.

Does anyone have one I can borrow or rent? Or know where I can rent one?

I live in San Francisco, but am willing to BART to pick one up.

Thanks.
