Hey Guys..I just received my 40" /window (model 20070810) from Sams..My local Sams did not carry it so I got it off of the website(free shipping!)..Question for the board..Does anybody else with this model purchased from Sams have the reduced chip loader and holder(reduced in half by a welded piece of metal) along with an additional metal box in between the bottom of the holder and the heating element? Mine does and I thought it would have been the older design.Oh well.I had the same layout on a 30" version with the window and had to take it back due to inconsistant smoke at the 225 .It wouldn't create smoke unless temp was above 250. Masterbuilt must have just change the layout because I saw earlier post stating the Sams model was the older chip loader/holder version.Fingers crossed I dont have the same issue..I'm preseasoning as I write and will smoke a butt this week end.I'll post to let everybody know if I can optain a good TBS.
