I have a three tier bottom draining system with no dip tubes. Clean up is easy, my BK and HLT are bolted to the wall and I've never had to remove them even for cleaning. End of my brew day I leave all the drain valves open and it drop dries.
Cons- I can't easily convert to propane or natural gas without custom burners. This becomes an issue since I'm moving and may not have access to the high amperage outlets I need.
