Roy K. Riches (sp?) is the only person I have found that is obsessive enough to have auditioned different consumer units, and the one he rated most highly is made by Memera 1000/2000 range, made by Eaton.
I have two, and they are certainly very good - no nuisance trips or other problems as I have experienced with some cheaper makes. It sounds very good too as I put in four MK double sockets, each on it's own circuit using 8mm sq T&E cable while I was redoing the lounge. Possibly overkill, but it wasn't too expensive as I had the floor up in the lounge. There is certainly no buzzes or clicks from appliances on the other ring mains and the noise floor does seems to be lower since this work.
Cheers,
A.
