I want the MES40. i know i should get the Gen 1 Back control style. But I'm new to electricsmokers and the window seems like the one ill want just so i can peak in but is it worth the extra money or should i just man up and get the solid black unit? Would make me feel more at ease Being able to look at he meat without opening the door. i know the glass will blur up but again will make me feel at ease seeing it through the glass. Also can anyone post a link to the lowest priced MES40 Gen 1 with and without glass? Thanks all!
