With all the talk about safety sausages, this seems like a good time to
ask for recommendations for one of these.  Is there a brand/model that
is favored by any of you. I will consider Halcyon's, but what about the
rest.

How about a favorite inflator hose air horn?

 I'm in the process of shopping for gear for the Cayman Islands. There
are a few things that I don't have because they aren't so practical
where I live. I will also probably buy a 3 mil wetsuit (instead of lycra
because I intend to stay wet and warm). Strike, if your new suit turns
out to be good choice, I'd consider that. But for a week of diving as
much as possible, warmth is going to be important for me.
