That is the base of the problem.

No just the opposite, they asked my opinion because of the difficulty  
and cost of wiring the antique building and I told them - NO - in no  
uncertain terms.  The contractor and his technical sub-contractor sold  
them a dream.  Dreams are soooo much easier to sell than reality;)   
Plus I told them that if they did it to be sure that the contract  
contain basically a satisfaction guaranteed or money back clause and  
they were romanced out of that also.

Rainer, thanks again for your common sense look at the problem.  Since  
I am basically forcing them to wire at probably double the original  
cost, I, like your mentioning, "the last time I looked", want to be  
sure that I'm not missing something that has changed.
