I guess you need to build this one yourself.
The trouble with gender changers is, that you can't just solder two connectors together - you need to cross the wires, so that the pinout stays the same (otherwise you'll get a mirror image)..
Why do you need this? Are you planning to build an IDE cable extension? I'd suggest you just create a custom IDE cable to your needs instead of doing lots of connections.. You'll thank yourself once you realise that you haven't had any data corruption. :-)
Please remember, that a cable over 50cm is too long in IDE world.
