My 2 cents:
Ceramic cookers are great! You can use just lump charcoal or sometimes wood chunks for smoking. Low and slow, or sear temps (600F+). My suggestion would be go with the larger of either the BGE or Primo. I have the Primo Oval XL and if you are cooking small, you can use the divider to cut the firebox in 1/2. I have most of the accessories (D-Plates, extended cooking grates, ash tool, grate lifter). In most cases all these are in addition to the cost of the ceramic grill.
BGE vs Primo can get into a Coke vs Pepsi level of discussion. They both do a similar job. You just need to review the sizes and pros/cons of each. Dealer support, manufacture support, etc. My decision was made based upon the oval shape as I do full spare ribs and like the width. Also, the price was a bit lower and it is made in the USA (if that matters). Also, you can purchase online and get support from Primo.
Either way you cannot go wrong with the final cooked product. For more information, there is a owners forum over at primogrillforum.com with tips, tricks and such. I am sure BGE owners have one also.




Now I am hungry!!
Good luck!
