LOL there is a lot of information. Just take it in and ask questions. I think the Naked Whiz review was the most informative for me.
To be honest, most of it didnt make sense to me until I started cooking on one! LOL but then again, i'm not technically inclined at all!
oh, and yes, you can be grilling in 15 minutes! Because of the way it 'pulls' air through and because the air has no where to go other than through the basket, you get up to temp very quickly. So if I'm grilling, I can be at 350F in 15mins without issue.
