Earlier quoted context omitted.

You can use mason jars if you are worried about plastic.

That works for things that perfectly fill a mason jar, but not well otherwise; the giant air pockets are an issue.

You can get differently-sized jars, though. I've got a pretty wide variety of sizes for different stuff.

I still use bags most of the time, because I don't think running a cooker at 55 deg C with bags rated for 90 deg C is going to be an issue.

Seems a bit exaggerated, and I'm not sure why, when this article was pretty awesome otherwise.

The professional-grade, ubiquitous Polyscience MX units are around ~$1000[1][2], and the low-end cookers start at $180-200[1][2]...

I've done some sous-vide after watching Chef Steps[1] on youtube. I just used a water thermometer and ziplock bags, which they have some examples of in their videos. My smallest stove top burner at its lowest setting gets water up to 117F. The salmon video they had the temp at 109, but I tried it anyway. It turned out amazing - I'd definitely do it again. I also tried steak, but bought a cheap cut, and it turned out…

I have a Sous Vide Supreme[1] and it's pretty much the secret weapon for making cheap beef tasty. Even cheapo chuck can do really well in one of them if you let them go for a while. What's nerdy-cool about it, I think, is that if you're quick, you can seal a steak with no air bubbles whatsoever and the steak will remain bright red while it cooks. Obviously you sear it after, but watching people's eyes bug out a little when they see the bright red slab of perfectly tasty and cooked meat come out of the pot is kind of amazing.

[1] - I also have an Anova, and if you can swing it I much prefer the SVS; with the Anova the temperature gradient can be pretty wide in larger containers, and you don't have to be nearly as careful about how you place stuff in the SVS.

It is way, way exaggerated. Even the professional Polyscience (the one I see in restaurant kitchens) only costs ~$800. HN'ers shouldn't pay anything like that: the current price point for consumer home circulators (the only kind you should get, like the Anova or Nomiku or Sansaire) is ~$160.

Sous-vide is interesting to me but only seems worth it if you eat a lot of meat. Am I mistaken?

You're not really mistaken. You can do some interesting things with eggs--very precisely control the texture of both the white and the yolk (which relates to the coagulation of different proteins). But, for the most part, I use sous vide for meat and, especially, red meat. I'm not sure I'd say you need to eat a "lot" of meat (it's not like I use my sous vide setup every few days) but it is primarily for meat.

"Average" is probably not the right word, but maybe the author is referring to full-on water baths, not immersion circulators? the Sous Vide Supreme Demi is between $300 and $350. A Fusionchef water bath is up to $2000.

Why would anyone buy either of these? Serious question.

I'm curious to see a graph of actual temperature vs setpoint. You're doing basic bang-bang control with a bunch of immersion heaters that get hot VERY quickly. And, dude, make that thing a little safer. Fuse your AC supply. Use real crimped terminal connectors. Put a safety enclosure around those immersion heaters or at least get them farther away from the wall of your chamber. Find a better way to secure them than e…

Agreed on the safety concerns, but I think the point of the project was learning, not saving money.
