Not one where you see what you want (alignment i guess).

<http://tinypic.com/ftn5nn.jpg>

was the last one, but i made no straight on shot and none from the bottom  
where most stuff is. Also, it's barely two sided, using only the pin  
headers as vias. Note that i use oblong pads so the copper you see on the  
left (where it isn't soldered top-side) isn't offset.
If you take care you can get the alignment just as good as with photo,  
it's the same task, but i still prefer single-sided quite often because  
without THP the second side isn't so useful to me.

Especially if you have no lightbox with light on both sides it can be  
tricky to align, and flip over, photoboards, as i remember.
