You reminded me that my instructions for making the SD-Card and PS/2
adapter for the original Spartan-3 board  were motivated/inspired by
those who do not have instant access to such things, or who might not
want to buy them.
The Digilent PMODs always seemed rather expensive to me, for what they
were, although less so now and it's not intended as a criticism - as
Chris says, their documentation is excellent (i.e. above average!). I
think across the industry (e.g. Adafruit, Sparkfun too) these kind of
modules have come down in price, due presumably to the "maker
revolution" and increased competition.
I was impressed by people soldering wires directly onto old SD-cards
(e.g. to stick them into breadboards) without completely melting them
 - and as it happens I did this again recently, to turn a
micro-SD-to-SD-card adapter into quite a decent micro-SD socket. Very
satisfying to use up old stuff lying around. Another meaning of
"off-the-shelf" I guess. :)
