Up for buy it now is a NEW SDL to USB Soarer's Converter cable for use with IBM / Lexmark / Unicomp Model M keyboards.  Each lot is for a single cable shown.  They are 6ft in length and are made of shielded stranded cable.  Each cable is fully tested with my IBM Model M keyboard and is guaranteed to perform flawlessly.  It does not drop data, does not require additional drivers, and does not timeout after periods of inactivity.  I've personally tested these cables to work with MacOS X, Windows 2000/ME, Windows XP, Windows Vista, Windows 7, Windows 8, and recent versions of Linux and Unix.  All Model M's will maintain their normal 2 key rollover when using this adapter.

Here's a simplified explanation of Soarer's Converter's main features:

Remapping - Assign any key to any other key, including ones that aren't on the keyboard, like media volume controls or the "Apple/Command/Windows" key on older keyboards like model M's.

Macros - A single key press can "play back" a series of key presses.  For example, you could set F12 to send Control-Alt-Delete or set one key to represent an entire shortcut like Alt-C for "copy" when doing copying and pasting.  If there's a certain combination move in gaming, you could set one key to perform the entire combination.

Function Layers - Changes the behavior of other keys when the function key is held down.  Think of this like adding extra "Shift" keys to add more functions to existing keys.

IfSelect - Press a key once and it permanently changes the function of any number of keys until that same key is pressed again.  Think of this like "Num Lock" which completely changes what the number pad does.  This is also useful if you are using multiple different operating systems or applications that you want different layouts from time to time.  Pressing one key could change the function of "ALT" to the "Apple/Command/Windows" key.  It also will allow you to have several different layouts programmed for different applications.  You can even program in completely different keyboard layouts like Dvorak or Colemak and toggle between them with a single key press.

I've written some basic instructions for configuring the Soarer's Converter under Windows OS, which is still a work in progress.  Be sure to read at these instructions BEFORE PURCHASE to see if it looks like something that you will be able to do: Simplified Soarer’s Converter Instructions.  Instructions for programming with other operating systems can be found on the Soarer's Converter thread on Geekhack.  Configuration is usually not needed for regular conversion to USB with key rollover preservation without the extra features like remapping, macros, etc. 

Other than the provided documentation, I can't provide a lot of tech support when it comes to configuring the converter, so again, make sure you check out the configuration instructions to see if it looks doable prior to purchase.

Shipping will be FREE to the USA.  International shipping cost is determined by ebay's shipping calculator based on location and does not include any international taxes imposed by the buyer's country (if charged, these taxes are to be paid by the buyer upon receipt).  Thanks for looking and please ask any questions you may have!
