I have a cloner I made out of the mister deal. It hasn't clogged on me yet, over 6 months, and I put it in my DWCs when I can. I bought spare discs which are pretty cheap considering. I don't know about an ebb and flow mister table per say. Heres a thought though, still have the table flood like a real ebb and flow and have the mister run all day to keep things moist and give them some food. I honestly don't know about a mister ebb though. I find they work best in DWC or DWC/drip type grows. I still use the cloner but I am obsessed with aero now so I have a couple aero cloners that get more use.
I might not be explaining well but I think it was munchbox who posted the pic of the external mister. Is the flood and drain going to have a dark area for roots, are you using netpots in a table above the flood area? If so run the mister in like a 2 gallon container with a lid and have a connection to your table so the mist keeps the roots moist, but still flood the sucker.
