In my debate on gas vs charcoal i've decided to give this guy a shot..
even though its grill area is only 22.5" compared to say 30".. i guess
from what i've seen it can feed 4-6 in one shot, but i guess its no
big deal to just add more meat when the first round is done.

Any comments on these:

Use lump coal, wood type too.. say pecan wood or mesquite or oak? If
grilling, no need to add wood chips, but if slow cooking add them.

Are the typical bags of charcoal in the store lump style or
briquettes? I cant remember..

If i end up with the newer model (not the 2005) one.. is it true the
gas is a disposable tank now, as before you could refill? Any
advantages to trying to retro fit the tank so it can be refilled?
Whats a typical refill cost vs a completely new disposable tank?

I've heard that the charcoal can often be used more than once? How is
this possible, do you not need to wait until the charcoal is
completely white (to avoid health issues) with this type of setup?

Cheers
