Just need to pay for postage/courier.

I made this myself about 18 months ago and it has worked fine except for the usual card reading problems.
Have to wiggle the card around to get it to read sometimes.
However it did seem to get worse (couldn't get card to read at all so there may be a problem with it - couldn't be bothered doing any troubleshooting) so I have upgraded to an Omnikey card reader.

It needs to plug into a serial port and has a molex power connector and standard 9-12V power socket (power supply not included)
I'll included the serial cable.
I just have it mounted in a 3.5" floppy drive mounting bracket so it has something to sit on.
