It's a shame that they don't have some of these out and around at local retailers. I bet they would sell a lot more if they did.
I had bought mine without ever seeing one either. Looking at the specs and photos really don't do the grill justice, once I saw mine in person, I was much more sure of my purchase.. then of course after using it a few times, the satisfaction with the purchase just continued to go up and up.
I personally have come to REALLY like the way the doors open... I think that design helps keep heat inside, and I actually feel like it just is easier to open doors to the side, rather then up... Only caution I have on the doors, is make sure you grab the 'spring' like thing on the handles, the rest can get quite hot.
Another thing, that I like a great deal about the PG500, is the ease of cleaning ash from the firepot. Just remove the direct grill grate, the heat deflector, and scoop it out with a spoon ( or vacuum it, if you really want ). I just scoop much of the time, often just letting the ash I scoop out fall down into the ash tray bellow... it very easy to just pull out the ash tray and dump that after. I surely don't miss having to take out the drip tray to clean ash.
I do hate to admit it... but because the drip tray doesn't have to be removed to clean out ash, because it's on a pretty large angle, and because there is no direct heat bellow it... I rarely clean my drip tray. It's pretty ugly , but since there's virtually no chance of that drip tray ever catching fire, I just don't feel much need to clean it.
Either way congratulations on your new PG500.
