We own a single and a double stearns inflatable. Have taken them on many trips over the years with no issues. The single I've owned for around 15 years and it's still working great. The saltwater (I've used it in the florida keys) fades the fabric somewhat, but I wasn't too anal on washing it afterwards, so that may be avoided. It's very comfortable, takes me 10 minutes to inflate manually, and weighs under 30 lbs.
Here's a link I found that may help...
