I have a Halcyon one-man life raft in like-new condition. Bought it for diving in off-shore conditions, and it's a great reassurance. However, I just got a Lifeline and decided to rely on that as my primary getting-lost protection, even though they serve somewhat different roles.
If you're stuck out on the ocean, there's really not any better piece of equipment out there for getting seen and staying warm until you're picked up. Be aware that it is very large--picture the largest SMB you can think of, but bigger--but it does fit in the common backplate pockets.

These went for $300 new. I'd like $150 for it, which includes shipping to CONUS.
