Do some reading on, "pelletheads" forum before deciding. Just like trucks and campers, there are tons of choices. I went with a green mountain grill brand and have been extremely happy. Mine came with a wireless remote so I can sit inside in the winter, and keep an eye on temps. The newer ones can be had with a wifi board that can be used with any smart phone. You can turn on your smoker, on your way home. Like turbs noted, it's great to be able to fill the pellet hopper and wake up to smoked meat! I did 40 lbs of pulled pork for our school teachers last fall.
Rectek and Yoder are other high end brands, but expect to pay upwards of $1500-$2000 for them.
Final word, Just like campers, dealer support can be helpful.
