Samtec charges a ton for their sockets, even in quanity. I know some of you have been looking to do large runs of boards with sockets. For most modules, the socket is the single most expensive part (besides the cable).
If you can afford 4 digit quantities, http://www.4uconnector.com/ has some that look to be correct. From the drawings, they actually look like the ones Gus is using:

You have to have an account to see the price, so I opened one. For these, they are $0.58 each in quantities of 1000. A buttload, but for you guys looking to sell zillions of modules, it makes sense.
Samtec charges $1.29/each in quantities of 1000.
Important note: if hand-soldering, the chamfering on the bottom of the Samtec parts makes it much easier. Look at the profile on a GHI module to see the difference when compared to a Samtec part. You may want to consider the through hole versions (4ucon part 06229) at $0.51/ea in 1000pc quantities instead.
Finally, if you’re going to have someone else assemble them SMT, you may need to get the version that has the cap on top (for P&P machines, presumably) and reel, which’ll run $488/700 pieces, minimum 1400 pieces. Part 19735.
Looks like the ribbon connectors are part 02291 at $0.67/each for 1000pc. Data sheet:
I stumbled across these when trying to find a cheaper source of MIDI connectors. I looked at the Sparkfun data sheet and found out they used these guys. (The 5 pin DIN MIDI connectors are $0.23 in quantities of 1000, in case you were curious. Part 05138 at 4ucon)
I have no idea what shipping costs from this place. Also, you have to “earn” sample credits by placing other orders.
