Sheesh, $42 for that book, cheapest. Thanks for the warning, I'm looking into the food safety aspects. I'm going to try the beer cooler method, it looks like if you start with a large enough cooler the water temp remains remarkably stable.

What's your opinion on browning the meat first vs last? I'm seeing these commercial device sites recommending that you brown first, then vacuum seal, then ice bath to get the temp back down, then sous vide. Other places say forget that, just go from fridge to pouch to sous vide and then sear the meat right before you serve it. The latter seems a lot less work.

If the beer cooler method pans out I'll cobble something together. A cooler, adressable thermocouple to measure temp, a remote AC switch to control an immersion heater, a salt water aquarium pump, and a laptop to control the whole mess and I think I can replicate one of fancy shmancy units for under $75. I'd start the thing off with the water close to the correct temp, my guess is the commercial immersion pumps are sized to bring cold water up to temp and cope with the addition of cold meat periodically, neither of which I need.
