Looking at the current prices, I'd say we (psubs, or maybe an interested group) ought to finance a white paper on manufacturing our own, and then produce a box full and put them on the market thru our own web page.
Tritech have nice altimeters:
http://www.tritech.co.uk/products/products-micron-echosounder.htm
Desert Star has a very accurate pressure sensor:
http://www.desertstar.com/Products_category.aspx?intProductCategoryID=6
Paroscientific also has very nice ones:
http://www.paroscientific.com/Depthsensors.htm
If you want to build your own depth sensor,
http://www.intersema.ch/products/guide/calibrated/ms5535-30c/
are a good start.
