You can make your own for under $300! Just buy the controller, $140, very large rice cooker $40-50 and foodsaver ($100ish) or some other device to evacuate the air out of bags.

I kind of laid out my setup in that Sous Vide thread in the kitchen forum.

My love to the Eades but I'd much rather have it piece meal so if something fails I can just replace that one piece, until I have more trust in their appliance's reliability.
