In regards to those connectors Knight mentioned: If someone really wants these connectors, I believe www.sparkfun carries them - but at a cost of about 0.75 cents apiece - not cheap if you need a lot, but if you just need a few....
And here are some additional pictures of a completed unit. With LED, socket, and wires out from socket.
The LED's to require a little bit of force to put push in, but it holds the LED really good. I've used this in an automotive enviornment, and when I do, I make sure to bring out either the cathode or anode, and wrap it over the back of the socket, so it won't come out.

I finally got everything wired up with the 110+ ICs (4017 and 4081 combo) to cascade the 4017's together. It provides 712 outputs for resistor / LEDs. I used a 4050 buffer (2 in serial but probably should have put them both in parallel) from the BS2px to drive a HIGH and LOW signal to all of the cascaded 4017/4081 ICs. I also used 2 more serial·4050 buffers from·a BS2px with a PULSOUT command to all 110+ 4017/4081s (to their CLOCK lines).
I can't beleive there·doesn't seem to be a problem with Fan out. I have not tried (not using) a buffer. I understand that the fan out rate is about 50 gates·for 4xxx series ICs. I really went above that limit and all is working well. The 7805 regulator does get a bit warm but certainly not hot to touch. I still have to read the current drawn on this monster of a circuit (15 solderless breadboards). I·will use 2x50 punchblocks (100 dual connections per punchblock) with 8 total at $11 each. I was going to use·about·(27)·25 screw terminal blocks but they were much more expensive. I like the idea of the punchblocks. I will post a picture at the end. I hope to meet with the customer this weekend to hand over the finished project.
PS: He will solder a 24 AWG wire to every 666 LED/resistors (supports up to 712 outputs) and punch them down to the punchblock (at his end).
Does anyone know where you can buy LEDs with about 12" of wire already attached ?
I have a client that is going to need several thousand. And I'm not gonna solder them...

Yes, Sparkfun's part is the same item, but jameco has them for $0.29 each when under 10, between 10-99 is $0.17, more than 100 is $0.10 each.
Jameco Part Number: 234798
