That is what may sway me towards electric, the convenience, plus the Masterbuilt is almost a "set it & forget it." Only problem is I'd have to bring out an extension cord... the 3-burner gas grill I don't have that problem and even fire it up in snowy winters for some steaks or pork tenderloins on occasion. Of course, with the grill's tank hidden behind it's doors, everytime I fire it up I'm always worried I'll run out of gas! I'm still on last year's tank right now on the grill.
I guess for me, each have pros & cons... I could always borrow the tank for the weedburner I bought & never used yet, or have a backup for the grill, or visa versa. But then that would be an initial expense not figured into the propane smoker costs. That's probably another $35 add-on. That closes the price gap between decent gas models and great deals on well-respected electrics.
Would you have paid $40-$50 more for stainless?
