I bought a sous vide a year and a half ago. I've not used it for honey but I can see just putting the jar in a pot of hot water and keeping the temps low enough can work for that. I don't have any need for crystalized honey - I usually need to measure out a tablespoon or so, and therefore do want it liquid for that.
I only buy local honey - much of the commercial stuff has dodgy backgrounds. And, not being a sweet tooth, I really don't eat it much.
I've discovered that I really like sous vide for chicken breast - you can find just the right temperature that the meat is COOKED, and before it turns tastelessly dry - and the whole thing can be cooked to the same temp, so you aren't overcooking the exterior to get the interior done right.
For steaks - only works if the steaks or roasts are tough, or if they are very thick - browning them after seems to defeat the point in sous viding a thin tasty tender steak. I was also not impressed with my salmon sous vide experiment. It tasted good... but why bother when pan frying them or baking them is just so much easier and at least as good?
