The Chargrill Akorn is a good product. ManCaveMeals on YouTube has very detailed reviews and cooks on the cooker.
Another product that you might want to use if you light the light and go method of propane cooking is the Weber Performer w/ gas assist start. It is a Weber Kettle which is one of the most versatile cookers, and you can load it up with charcoal and hit a button and the propane will light the coals for you. The Weber Kettles can be used for smoking low and slow, indirect and direct heat grilling, and capable of cooking pizza's. It utilizes the one touch cleaning system which makes clean up pretty easy, as the ash will fall into the catch pan (not tray) You can close the bottom vents as well as the top vent and it will snuff out the coals so you can reuse them as well. It isn't as efficient as the Akorn is, but another option that also offers a work table on the side.
