I can well believe this - and in that case, why do a lot of the board houses have the so-called Prototype 
minimum of 5 pieces?  I know Olimex will do one-offs, but most of the others won't, which seems a huge waste 
of money.  If you discover problems only "using" one board at each iteration, you have 7 * 4 = 28 wasted 
boards!
