If you do decide to go electric, consider what I use Masterbuilt Electric Smokehouse or MES. There are two models 30" & 40", personally I think the 40" is the way to go, you can really load it up with food, easily smoke 16-20 racks of ribs, or just 2 racks. I purchased the 40" for 2 reasons, 1st 3 to 5 times a year we do a big BBQ feed with family and friends, so I wanted the capacity, 2nd I like to just lay the racks of ribs on the grate whole, without having to cut or roll them (the 40" is wide enough to allow you to lay out the ribs). The BBQ smoking forum I frequent, the MES has become the electric smoker of choice. The 40" is $299 at Sam's club, and can be more expensive at other outlets.
After reading hundreds of post about the 30" & 40" there is another reason to choose the 40", it just seems to operate better than the 30".
