  Eagle works brilliantly for single sided.  Only open the second layer 
for the correct passes and cost it properly and it will produce 
excellent patterns with minimal jumpers to install where the 2nd side 
traces are.  Easily as good as a person at smaller boards, and clearly 
better than a person at larger ones.  Just watching it work on a medium 
sized complex board and the lengths it can go to to elminate or length 
minimize the out of main plane traces, it's very clear that it's well 
beyond what most people would come up with for the same board.

  Only real complaint would be not the 2nd layer traces cross, which is 
easy with insulated jumpers.  But thinking about it now, duh just make 
it a 4 layer board, 1 low cost, 1 highest cost, 1 highest-1, and 1 
highest-2.  Nothing but a breeze to do..
