I love my gasser! I had an electric unit and trying to keep the temp where it was supposed to be wasn't as easy as it should have been! Even high dollar electric ovens have issues with their thermostats so you can imagine the variation with an electric smoker. Since yours doesn't have a thermostat you have other issues in that you cannot add heat to compensate for a cool blast of air, or add some additional heat to almost sear the meat, etc.
All of that I can do with my propane unit and, so far, the gas has been far cheaper than the charcoal though not at all as cheap as the electric!
I got my
Masterbuilt Gas Smokehouse for Christmas and am only on my fourth tank and I have done several long smokes to include a couple of briskets, some ribs and some butts.
My electric never gave me a smoke ring like the gasser does. Yes, you can add charcoal to get that ring but then you're increasing the cost of operation.
My electric had to stay near the house, my gasser can go with me.
At least you have, in my opinion, the least problematic of all the electric units out there since the element is big enough to truly do the job and there are no issues with thermostats, wiring and so on, truly a set and forget device. Big problem with your unit is you cannot go down to real low temps for cold smoking fish or drying jerky. All of this I can do with my propane unit.
