I have products from both. I have successfully integrated the Delfina Flipper in with my Mediator system as well as in my A1200, which has an Elbox IDE splitter in it. The Subway, unfortunately, is a different story. I have not been able to get it to work at all, in either machine. I've tried clockports on an X-surf, BuddhaIDE and a Kickflash, and the A1200 MB. Frankly, its been very frustrating and I've pretty much given up. I'll either try to get the OpenUSB PCI card going again or wait until e3b releases their new ZIII USB card. btw, the situation described in the original post about the A1200 not booting with the subway attached? Same exact problem I had.
