Yea you first couple of posts will have to be approved by the moderator. Its not very many and then you won't have to deal with that. I think it is used to cut back on spamers maybe???? Not sure but it will be over very soon.
As far as Propane vs. Electric wood burning its all a toss up. Its like the Ford, Chevy, Dodge thing. (Ford is better though
) Everyone has their own likes and diss likes its pretty much a personal preference. Most people actually have several smokers so they have a variety. I personally have never had an electric so I can't comment on how they run. I have two propane rings and one UDS which burns charcoal/brikets/Lump wood. You can get a lot of smoking out of one LP tank. I can't say for sure how long because it would depend on a lot of things, wind, outside temp etc.
Hopefully someone with experience on an electric will be along soon to throw some input your way as well.
