The trick is probably finding a good board house that still caters to the
single sided board market and does enough volume to take advantage of the
lower cost.

I think most board houses saw that the future of single sided boards is dead
and went with new equipment and stock that assumes at least double sided.
That new equipment is expensive up front, but allows them to crank out
boards very cheaply and pass the savings onto you as long as they do enough
volume to utilize it fully, It's quicker and easier for them to run a common
(2-sided) board through their equipment and processes than to do something
out of the ordinary - even if that out of the ordinary something is more
simple.

Now if you are building the boards yourself, it still holds true that more
simple is less costly.

Really?   This doesnt quite have the "ring of truth" to it.
I mean.... the entire plated thru process is skipped.
And I gotta beleive that single sided stock is cheaper
than double sided stock.

And as far as longer etching time for double sided stock....
I dont beleive it.
