I've had great luck with my Akorn and used it 4-5 times per week since buying it last June.
No complaints other than maybe wanting more room. Heck...a second Akorn would fix that, though.
200 degree ribs for six hours....then open up the vents while I'm slicing the ribs onto a serving platter.....then 600+ degree ribeyes. An ultimate meal. Same load of lump.
I've never had a UDS but would like to learn more about them.
