I'm new to SMF so please be patient with me. I'm not sure of the rules (I'm at work so really can't look them up) so I won't post any links. Im interested in purchasing the 1st generation MES. I found a website that has them for $349.00. I called masterbuilt and they confirmed it is indeed the first generation stainless window smoker. My question is, are there any disadvantages that the 1st generation has that the newer model may not have. Basically I would like to hear from owners of the MES both 1st & 2nd generation who may have some valuable opinions. Thanks in advance.
