Hello! I currently smoke with a 30" MES - Has worked great! The one annoying thing is that it's not wide enough to cook a full brisket - or sometimes a full rack of ribs... So after a bunch of research - I think I'm going to go with a 40" MES - I think it's got the best bang for the buck - Though a Smokin-It Model 3 had caught my eye... I've found 2 versions of the 40" MES that have my attention... There appears to be a "standard" Masterbuilt version 20070215 that has a glass door / Bluetooth, etc. etc... There's also a Cabela's version 20071115 that looks more like my 30" MES without the glass door. My question is: Would spending an extra $100 be worth it to eliminate the glass and get 2 extra racks? My thoughts are that the glass is place for heat and potentially smoke to escape not to mention a bit of extra time to clean... However - i'm planning on using an A-Maze-N pellet box in it - So the glass would be nice to see if I lit it properly see if its burned out or something like that... (Though i guess I could tell from the smoke coming out of the unit) Thanks in advance for any thoughts or opinions that can be shared!
