I have parts to make about 3 extra of these beyond what I need. If anyone is interested, shoot me a PM.
Price: $30 each + Shipping. Would prefer to sell these to Amigans in the USA, since international shipping would likely cost more than the actual item (except maybe to Canada).
Capabilities: Can program any TWO Kickstart images you want onto it. If you want 3.1.4, you'll have to provide proof to me that you bought it from Hyperion (send me a screenshot of your digital download's receipt). You switch between them (WITH THE COMPUTER POWERED OFF, OF COURSE) by moving a jumper. You can also wire a DPDT switch onto the jumper posts and attach the switch to the external of your case.
You will need to tell me what Amiga you are using them on, INCLUDING the revision of the motherboard if you are using it on an A500, because I have to change the solder pad jumper configuration if you have a Rev 5 or earlier board.
