Another vote for the O-grill. I beieve it is the cast iron grill that makes this thing work so good, but it works great. Basically have started using it at home instead of the wire rack propane grill I have.
The O-grill does clean up very easily also. On my lance 825 it will fit in the generator compartment, but usually rides in the truck. I have not tried any others so my opinion is partial but it really works great.
It has a built in regulator and you can hook it directly to your auxillary propane outlet if you have one and get the hose. I have not tried this as it seems like I would loose the propane in the hose each time I disconnected it. Anyone have experience doing that?
