I just had to try it....always wanted to, but won't spend the ~$400 on the real deal. I'm aware of some of the food safety items I crossed, I'm sure there is more, live and learn, I will always be open to learning more.Here's what I did: I put my temp probe in my small crock pot last night, filled with water and set it at "keep warm" setting. After 3.5 hours it settled right near 140 degrees. So, this morning I went to the store and bought these 4 little steaks (eye rounds 3/4 inch) for the cheap price of $4.28. I sprinkled some homeade Montreal seasoning on each, a dash of A1, and vacuum packed em. I ran the tap water to about 120 degrees before filling the crock pot, vacuum sealed the cheap steaks, and set em in. I returned home 6 hours later and the temp was reading 140 degrees. I pan seared each over EVOO high heat, about 45 seconds per side, then cut to eat, no real resting. The wife and kids wouldn't be home for another hour, so I ate one by myself, and wow was that tasty steak!! When they got home they also really enjoyed this cooking method, I may have buy a new large dial setting slow cooker with external temp controller!! I'll try to put the pics in order...ok, won't let me load em atm, I'll try again after my next beer
