I'm posting this under a new title because I've seen a lot of replies to
the original thread where people are talking about hopping all over the
$100 dollar solution. Be _very_ careful about the less expensive
"options" and your own crockpot. These cheaper units usually have a decent
temperature control system but they don't circulate the water like the more
expensive units do. And according to a lot of what I've read, the
circulation of the water in the sous vide bath is important to the end
quality of what you're cooking.
