You do need the electric motor for turning the hog, but as far as the propane goes, I think you will be dissapointed.
If you do decide to go the wood route, it does require you to be around most of the time to make sure none of the fires burn out but it does not require constant care. If I were to guess, once the fires are going, I add about 1 peice of wood on each fire approximately every half hour or so.
Myself, I enjoy sitting beside it with a cooler full of beer. To me, it's like a good movie that lasts 5 or six hours
and if you haven't already, you'll meet just about every neighbor on your street
Which ever way you decide, It still a good time no matter what. I'm drooling just thinking about it but next one won't be untill Christmas however a lamb could be in the works shortly!
