i thought about getting a griddle but i dont think id use it enough to justify. plus i figure ill just get a griddle plate to lay on the gas grill side when i need it.

I picked up one of these a while back, Lar.  Twin burner.  It is one hot mofo.  It will easily put a good char on a burger.  I like to use it to brown meat for stews.  It's better than a pot or skillet since the juice doesn't pool up and ruin the browning.

Add an adapter to fit it to a tank, and you're set (unless you want to buy bottles).
