Hello, Edit: it is a first gen 40" MES, not 2nd. Thanks Bearcarver. I've been planning on getting the 2.5 gen MES 30" from Home Depot once it went on sale but then yesterday Home Depot stopped selling them and replaced them with the 2nd gen 30" models and 1st gen 40" model, 30" no window $399, 30" window $399, and 40" window $429. The 2.5 is still listed on their site but with no price (previously $399) and cannot be ordered. Is it better to get the bigger, $30 more expensive, older model, than the smaller, slightly cheaper, and newer? Or should I hold out for a 2.5 30"?
