Windows BMW dealer software cable for programming Bimmers

Just bought my first BMW, a 2002 525i with 130K miles on it, so I downloaded the dealer software (INPA) for changing settings such as the automatic locking at 5mph (which I want to turn OFF!).
Since I have a Windows 7 machine with USB (but not serial ports), all I need now is the $20 cable to go from the 16-pin OBDII connector near the driver, to the USB port on the Windows 7 laptop.
It seems most cables online are for the newer (D-Can) BMWs, and because of that, they're more expensive ($50) than I need ($20).
But I just want the older cheaper BMW cable (with pin 7 & 8 as the K-Line).
Do any of you have an older (1997 to 2003) BMW that uses the older K-Line cables?
Where did you get your cable?

Googling for "bmw inpa cable k-line e39" I find more than I can shake a stick at. Unfortunately, most are K+Dcan, which is fine, if both pins 7 & 8 are K-line (as I don't need Dcan for a BMW E39).
But, almost none of the ads state which pins are for the K-Line.
For example: $32 (Amazon.com product link shortened) $30 http://www.bonanza.com/listings/Inpa-Ediabas-Sss-Ncs-K-D-Can-Obd2-Usb-Interface-For-Bmw/162319547 $25 http://www.ebay.com/itm/like/201047893380?lpid
What I'm hoping to find is a Windows user who owns a BMW E39 (i.e., any BMW 5-series from 1997 to 2003) who works on their own car.
The theory is that, if you work on your own car, you'll likely already have the cable.
Then you can recommend which one you use that works with INPA on a USB Windows 7 laptop & an 16-pin OBDII BMW E39 connector.

Can you make your own cable out of one of the above?

For two reasons, I am not likely to make my own cable. 1. I don't know what I'm doing, and, 2. It would (almost certainly) cost more than the "right" cable
My problem isn't finding cables that are supposedly for the BMW dealer INPA software.
My problem is simply finding a cable that I know is both a good cable and a good price.
For example, I don't know if this cable is worth the $100: http://www.one-stop-electronics.com/shop/?dispatch=products.view&product_id 
Or, if this similar-sounding $40 cable is just as good: (Amazon.com product link shortened)
Or even if this seemingly too cheap $19 similar sounding cable will suffice: http://www.ebay.com/itm/like/281306380016?lpid
The only real way to know, is to ask someone who already owns a BMW who would likely know the answer, if they work on their own car.
Since most BMW owners who work on their own cars use the exact same software tools that the dealer used in 1997 to 2003, all I'm trying to figure out is which cable will work at a good price.
Are there any Windows BMW owners who work on their own bimmers who have the INPA cable who can then provide the advice I need to select one at a good price that allows me to program and code my new BMW 5 series?

Your application is pretty standard for BMW owners.
However, most older bimmer and even the beemer owners actually used the Windows XP *serial port* INPA & GT1 cables, specifically tethered to the venerable IBM Thinkpad T30 laptop.
So, while you're using the *same software* as the dealers used in the late 90's and early 2000s, your laptop is likely slightly more advanced than what the BMW dealership used up to about 2010.
Even so, you *should* be able to find a bimmer or beemer owner who has the USB cable, since most would have used INPA, EDIABAS, NCS, DIS, GT1, and/or Progman on Windows XP to code options, program modules, reset functions, clear error flags, and read codes.
Maybe try alt.home.repair? Those guys know everything that goes in a garage. (Ask them about huckleberries, for example!)

WHICH you can use, in combination with an external usb-to-serial device. --scott

Are you suggesting a USB to serial converter added on top of the cable?

Very easy. I use Keyspan. I use it to access my Anthem AV receiver to run ARC. The receiver has only 9 pin serial port. Not many Desktop or Laptop has serial port aany more. I use it on my OBD II utility as well.

If you are using a cable that has a serial output, which is what the cables the dealer used to supply were, yes. --scott
