I use the camoflaged World Class SOSpenders. Got them on sale last yr and never looked back. Saw Sport model ones for as low as $59.88 plus shipping via mail order.
I went with manual inflate. I am in the surf most of the time and get splashed too much by water so the auto one I was afraid it would be going off on the time.
My 6 yr old daughter was the driving incentive to get the SOSpenders. My wife would just have TOO much fun without me!
