Wondering as it is both a time sink as well as a cost, we are getting UL and CE certification as well as FCC for MMR.
I believe that FCC is required, and I believe also that CE is required for export to Europe. UL is not 'required' but I think that some formal testing at least should be done to maximize consumer safety ... seems like from what I'm hearing that they do pour tests, lots of ground tests, shake tests, tipover tests, as well as all of the electrical tests (which from the reports from Chicago Gaming we are doing fine with ...) but it takes time and there is alot of hurry up and wait (no change to current mmr schedule).
Anyways, I think this is an important topic and would be interested in what the other vendors are doing to address both the 'required' and the 'desired' testing ...
