Are these an enduring, "better" way to grill, or just a passing fad? What is the operating cost vs. propane? We have a 20 year old Weber Genesis propane grill which has served us well and still works. Though I have a preference for the "added value" of charcoal, the wife wanted convenience, so we ended up with propane. I've tried the smoker tubes with wood chips to get some additional flavor, and it does work, but requires some setup and attention during the cooking process so I tend to not use the smoker tube often. I have some buddies who have been extolling the virtues of pellet grills: one has a Traeger, the other a RecTec/RecTeq. Yet another has a GrillaGrill. I see that just about everyone makes pellet grills these days, so I'm not sure whether these are a new and passing fad, or whether they really are better. As I understand pellet grills, the advantages are the easy of use, mild smoke flavor, and the automatic temperature management: you can start them with the push of a button, smoke for hours without much manual intervention, and crank up the temperature for shorter-duration grilling or searing. However, I've never used one and know little about them. Not sure if I'll go broke feeding them pellets. Not sure if the difference over propane is worth it. Not sure how they handle different climates or seasons. What say the PoA community?
