Home Distiller

So i've planned out my column, but i need help with finding a good boiler. Obviously a keg is the cheapest choice, but im wondering about the ease of use, the size (i plan to distill ~8 gals in a run) and how easy it is to clean (meaning that i want to be able to detach the lid/column to clean if doable)

For me an extra few bucks is worth having something i can clean when needed.

Any thoughts? thanks!
