I had a look the spider but would prefer a cheaper alternative if it's possible?
There were people re-flashing NEC USB cards to work with the Mediator a few years back. Some throuh this site and some on Amibay. May be worth asking at Amibay and EAB. If you're good at soldering and have an EPROM programmer you may be able to do it yourself if someone can provide you with the required firmware.
