Its a bit crude but...

To make a one off development type board I will sometimes, when faced
with nothing but an SOIC, take a VERO microboard and cut the copper
long ways down one of the 3 hole pads with a sharp knife such as a
"Stanley Knife". The spacing is now SOIC.
A dash of solder paste, a quick run over with a hot air solder
pencil.... problem solved.
Alas TSSOP etc is seriously out of reach with this method.. its a pcb
or nothing.
