Have had a electric Brinkman for yrs. Very simple and a no brainer.It keeps a constant heat that you can't adjust. It is what it is , and a temp thermometer helps you to see what temp it runs on average. No cleaning except racks and water pan.
You should have a good power source because it pulls alot of juice. An outlet away from your house is best and helps to keep the smoke away.If you use an extension cord you need a big one to carry the load. No cord is better.
Elements do rust out after several yrs. and Bass Pro sells them for 25 bucks. Have had this smoker close to 15 yrs. now.
Neighbor gave me brand new charcoal identical to my electric one. I think its a brinkman too. I added an elevated rack to keep the charcoal about 1-1/2 to 2 inches off the bottom and it works 100% better.
Once you master how much charcoal to use it is a great way to smoke. It also has a built in temp guage that helps alot.
The only downside is you have to get rid of the ashes.............No big deal
And buy a cover for it too!
