I've done both fire and electric.
Been a judge in numerous BBQ contests. Used to be a BBQ snob, and looked down at electric until a friend showed me a Masterbuilt electric.
For 99.97% of the population who doesn't do BBQ in competitions, electric is the way to go.
Prepare your BBQ, load the electric smoker with disks or pellets, set the temp, DONE.
No worshiping the fire smoker every couple of hours with new fuel, or worrying about weather vs. smoker temp.
I have the larger Bradley and LOVE it. Looked at the Traeger and Green Mountain. The additional price vs. features was not worth it to me.
Bought it online at Home Depot. It was cheaper at Walmart Online and Home Depot matched. Disks I order from Amazon.
Just noticed you were looking at the 4 rack Bradley. Wait for the 6 rack to go on sale and you can get the 50% increase in volume for the same price. I use all 6 racks all the time as a single brisket won't fit on one rack and has to be cut in two to fit on two racks.
