I went on ahead and pulled the trigger...I ordered the older version, model 44241GW vice the newer model PS4415 for two reasons:
1) two cabinet door latches about 6" from the top and bottom, vice one centered half-way down the door length on the newer model. I'm thinking the more latches the merrier on this decision.
2) The smoking bins on the older model will not only hold chips, but chunks as well. The newer model, although nifty in its approach for simple pull out chip bins, you can only get chips in them, they're not very deep at all and they have a hinged cover on them. Bad thing is, they hinge on the front of the chip bin, not from the rear end away from the handle, requiring the bin to be physically removed to add. Why not hinge the damn thing from the rear so you can pull it out about halfway, sling chips in, and slide it right back in?? Duh!!
The older model, come to find out, has two 12K BTU burners vice the newer model having twin 11K BTU burners. Not that big of a deal though when it comes down to it. Most folks smoke with one burner only, when the smoke stops on that one, fire up the other one, and kill the dead one until you reload it, having it ready for the next heat/burner swap. You can also access the older version water pan through the bottom latched door, instead of the newer one, the water pan is accessed by opening the grocery door.
I didn't order through Sam's, I ordered through Home Depot. With my 10% mil discount, that got bumped up to 15% because I got the run around on the 1-800 through a cust svc rep who had zero idea or clue as to what she was telling me on the phone, until I got her supervisor on the phone. The 15% off saved me $51 and some change. Free ship, will be on my property NLT 25 Nov.
