FMA has a curious attitude toward dealers and customers.  They  
sometimes act as though we are the great unwashed and shouldn't be  
asking questions; we should just buy their stuff and use it, because  
it's the best you can buy.  If you don't believe me, just try asking  
a tough question to one of them at the Toledo show in a week or so.
