Hi Tom,
LOL. Yes, the beer can chicken is worth it. I do that about 1 - 2 per week. Just buy the beer can holder, put a 1/2 can of beer in it, marinate (I use different things) the whole chicken (take out the insides of course) for a couple days and then put the chicken vertically on the beer can.
I like charcoal and use a Weber Gold. I use a charcoal chimney (eliminates lighter fluid) to heat my coals. Once heated blood red, I pour them in the grill and spread around the perimeter, so to leave an opening for the beer can chicken to rest. I put it in the center of the BOTTOM rack (leave off top rack) for 20 minutes (indirect). This gets it going and a bit charred - awesome (but not burned). Cover with grill holes open.
After that, I transfer the chicken to the TOP grill for an hour or so (180F), again, in the middle (Always cover). I put the soaked/drained chips on the coals after the first hour.
Some put a few new coals on every 1/2 hour, but I've never had to with the chimney.
Be careful when you take the finished chicken off the beer can (extremely hot aluminum can) and never drink the beer - you'll end up with beer can chicken and burned tongue
You will never have a more tender, more awesome chicken
Sorry for OT
