So an update for anyone interested. I finally made a decision (took long enough) and bought another MES 30. Cabela's has a great sale on it right now, so the total was $168 after the $10 email sign-up coupon. I was seriously considering the Smokin-it 2D, but at $600 cheaper, I just decided to go this route again. After all, I was happy with the results I got from my last MES. Also ordered a Thermopro TP25 4 probe Bluetooth thermometer, so can't wait to try that out also. :)
Thanks everyone for the advise and input!
