"I'm with Roman, I think building a big through hole board belongs in one of
the circles of hell. All that flipping over and having parts fall out,
clipping leads, burning my fingers as I try to get the parts tight to the
board, etc."

You are doing it wrong.  I never "flip the board over" -- I solder all parts
that have equal height at the same time, and place them against a small
piece of wood before setting the whole thing down.  It's all about order of
operations: 

1) jumper wires
2) diodes
3) resistors
4) IC sockets
5) ceramic caps
6) film caps
7) TO-92 packages
8) electrolytics

If, in that rare circumstance, I need to flip the board over before all the
joints are soldered, then I simply pick up the piece of wood and invert the
board into my other hand -- nothing ever falls out.

Also, if I do drop a part on the floor (a very common occurrence), then I
can generally find it and pick it back up.  Not so with an SMD part -- once
it hits the floor, it is in the Delta quadrant, sinking in Captain Janeway's
coffee.
