hmmm,  guess those last couple of boards I did shouldn't have worked.

Like I said, I've found that I dont really need expanded pads.  If I 
can drill the holes pretty accurately, anyone can as I am pretty much 
of a klutz.  check out 
http://www.geocities.com/phil1960us/pcb/index.html for some examples 
of pads and holes I've drilled using standard Eagle libs.  Maybe they 
are bigger than your design SW/libs to start with.

Yeah, we agree here.  start big, work your way down.  A year ago I 
didn't think I could do DS, 10 mil trace boards.  Now its like my 
gold standard.

absolutely.  they have one of the most generous sample policies 
going.
