My wife found a 30" MES on craigslist for 75.00, I have contacted the person but no response just yet. Anyway my question is this, I have heard that you should not use a extension cord. Because I do not have an out door plug, I am left with two options.. 1) Use a cord. 2) Use in the garage, with door up. SO I was wondering if it was possible to use a cord, and just how much power loss should I expect. Also I am wondering just how smokey they are? Are they as smoky as my char smoker... or is it less smoky, if so is it possible to use in a garage, or will it ruin everything in the garage? Thank you, Duane.
