I agree with Merlin2375. Far as I'm concerned, after looking at all of the available models and reading everything I could find, the
Mustang Model 3184 with hydrostatic release, 5-year no maintenance, and built in
harness is the way to go. I bought one, loved it, and bought two more for my crew.
Best price I found last year was at Star Marine...I bought two for $472.85, including overnite shipping. I have two red ones and one black one.
Here's a pic of one in use by the off-watch:

They're really comfortable, so we often leave them on during passages even when below.
