I was looking at pellet grills before I found the 560 Gravity grill/smoker.  I am so glad that I purchased it as the flavor of the food is so much better than anything I've used before.  It's also great as it can smoke and grill amazing food. The only issues I have is that the temperature read out is over stated by about 25 degrees, which is a lot if your cooking low and slow.  The other issue is the burn rate of the charcoal.   I started out using lump charcoal and had to refill the chamber 3 times for a 12 hour smoke at low temp.  I then switched to briquettes and while they did burn slower, it wasn't really that much of a difference.  I filled the chamber 2 times for a 13 hour smoke at low temp.  So the 10-16 hour smoke time that they advertise is not even close.  It's the only reason, I didn't give the grill 5 stars.  You will go through a lot of charcoal.
