I just got a buddy heater for Christmas and it is great. I originally wanted it for ice fishing, but will use it in a hunting blind next year. The buddy is ceramic and is very quiet. No hissing sound what so ever. The nice thing is it has a low O2 sensor that will shut it off so you will not die from carbon monoxide poisoning. This means you can use it in an enclosed blind, camp, tent, whatever. I used mine the other day in a portable ice shanty on an 8 degree morning. Turned it on high for a little while, then turned it on low. The shanty was toast warm. As the sun came up and it got to about 15 degrees outside, I turned the dial to pilot and this kept my pop up nice and cosy. The black cat and sport cat are smaller to pack around, and may also be a good option. I amgoing to get the sport cat for hunting next season when I hike over some distances. It is more packable then the buddy, but only kicks out 1000 btu's. Enough to keep warm when needed, but not hot enough to start anything on fire. You can put a piece of paper on the element on it and it wont light. Pretty neat!
