Interconnect Cables

What are others using for "component interconnection cables"?
I'm thinking generally in the long term, and specifically for the RFID reader (4 conductors) in the short term.
I'd like something like the LCD extension cable:

I've found ribon cable, pin headers and end connectors that I could use to roll my own (Digikey, Jameco, etc.), but was musing after something ready made (avaialble in various lengths).

If it's a digital output device (spits out rs232) then I'll just CAT5 cable...unless it's a REALLY noisy environment, then I"ll use something shielded and twisted.
If I'm doing simple breadboard things, I use the single wires from CAT5 cable (solid core)....
I'm a scrounger and love using old cable....

If you have the newest DigiKey catalog, (can be downloaded) look at page 80.
With the following part numbers you can create a cable, without having to crimp anything.
Quantity: (4) PartNumber: H2BBT-10112-S4-ND
That's a 12 inch length, and you can find any different sizes ranging from 2 inches to 12 inches. If you need more than 12 inches you can call DigiKey, and I have talked them into making me cables with longer lengths (they make them at thier distribution center), I got them to make 26 cables of 3 feet, so I know it can be done. The charge wasn't bad, it was something like $1.25 each, if I recall correctly.
Different wire sizes, everything...
Take the socket, and plug the wires into the sockets. You can create any array of wiring since you're making the cables, yet there wouldn't be any crimping needed. Pricing is decent for prototypes, and small runs of products.
The wires could be purchased in about 7 or 8 colors, so you could "key" the sockets. You can also get a socket with a larger number of connections than are needed, IE, get a 5 pin socket, and put a "key plug" inside the side pin, so you'd get | pin1 | key | pin 2 | pin 3 | pin 4 | This would allow keying so that no one could connect it incorrectly oriented.
As for the length of a RS-232 signal on TTL levels, It's probably not a good idea to go over maybe 5 feet?.... The RS232 spec (which remember is at voltages of 12V's, not 5 as with TTL) is something like, 15 feet without a repeater or amplification. However, I have gotten it to AT LEAST 100 feet with standard cat5 cable (to program a Basic Stamp at that), however I would suggest shielding if going over 5 feet (TTL or true RS-232).
