I bought a CED 6000 last month.
It was not my wisest hour. My last club used PACT-IV and PACT-III timers, and there is a world of difference. The auto-power-off function stinks and the operation is rather counter-intuitive.
I sent it back (thanks, Dillon) and ordered a PACT-IV. Heck, I need a chrono anyway, and it is a great timer.
