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..
