[sdiy] surface mount sans PCB?

Here's what I do for surface mount DIY.
I get a Radio Shack universal PC board.  The one with the two bus lines
snaking through the whole thing and the IC spacing.  There are sets of pads
with three holes each. I cut these pads in half length-wise with an X-acto
knife so that they are half as wide.  At this size they are perfect SOIC
spacing.  Then I remove the bus traces on either side of the pads I've
divided in half and run bus wire from the half-pads to the full pads on the
next set over on each side so the leads go out in a spider fashion from the
home made SOIC "socket" to the pads on either side.  Then components can be
mounted on these pads and the SOIC chip can be surface mounted to the half
pads.  
This has worked really well for me, maybe it will for you.
Good Luck
