Window is nice but after a couple hrs into the cook you can't see thru it anyhow. I would suggest going with the 40" also. I along with others have done the mods ( PID & Mailbox mod) , it is a set it and forget it smoker.
Im a little overwhelmed with all the different models to choose from. I had no idea there were so many of the same kind. I think I will just go for the 40" model for its better to have more space than not enough.
I would like a window but I dont have to have stainless.
Need the side chip burner and prefer digital with some kind of bluetooth or IR remote would be nice.
It sounds like a good warranty is in order with the digital boards.
Where is the best recommended place to get this?
I've had the 30" and 40", it's a natural evolution thing. I'd suggest bypassing the window - it's neat, but, doesn't add to the cooking capability, may be a heat-loss part of the smoker, and requires constant cleaning if you want to view through the window. Basically, it costs more, adds nothing to the cooking capability, and requires more maintenance.
I've had the amnps since day one. When it works, it is wonderful. It works about 1/2 the time. After 5 years using it, I can not say that I've found any method to make it work consistently. It's a very nice add-on, since when it doesn't work all you have to do is keep feeding the chip tray - no big loss.
Keep your eye out for Rural King, Menards, Walmart, Orscheln's to have sales on the MES 40.
Good luck.
