I'm a big fan of the SousVide Supreme machines, though the price is usually too high to justify one. They are currently running a special where you can get the Demi for only $179, which is $150 off the normal price. It's a good deal if you are looking for a sous vide machine and puts it in range of the usually less expensive circulators.
For the next 5 days you can get $150 off the SousVide Supreme Demi, taking the price down to only $179. You can order it here. Just be sure to put in the code DEMI179 when you order it. This offer is only good until May 17th.
