I use Weber gas and charcoal kettles, but recently was looking at these wood pellet fired grills

BBQ Grills & Smokers - Traeger Wood Pellet Grills

No flare ups, precise temperature control, up to 20 hours of. Urn on low heat with a full pellet hopper, etc.

Very intrigued by these things.

Anyone have something similar, used one, etc?

Thoughts?
