I'm selling my ICE TUBE Clock complete with spare tube assembly. It is built to space flight standards (literally) so the workmanship is beautiful. If you are uncomfortable with building your own but you still want one this is your chance. Not looking for profit, just to break even. My pleasure is in building complex things, not necessarily keeping them! Will be on ebay from 9/23 to 10/7. Just search ICE TUBE clock.
