No personal experience, but I've heard good things about the VDO system - apparently you can add their speed sender to any one of their electronic speedometers (
VDO GPS Speed Sender | VDO Instruments and Accessories).
While all of their speedos will have VDO printed on the face, they do have a wide variety of styles to allow you to (hopefully) match the gauges you already have, albeit no 'reverse-wind' models.
