Some big players entering the sous vide market. Still an expensive tool, but we're starting to get better tools for less money.
The Sous Vide Supreme Demi that I have is $330 on Amazon, with a max capacity of 8.7 liters (2.3 gallons). The full-size SVS has a max capacity of 11.2 liters (2.96 gallons). It does a great job, but you're not going to get a lot in there at once.
PolyScience just released the
Sous Vide Discovery at a sub-$300 price point, with a max capacity of more than double the Demi at max volume 20 liters (5.3 gallons). And it's not tied to a specific tank. You can buy different tanks for different applications.
