I think it's great your getting that much for it! I just remember years ago
when I was making the first 20 of mine, some people were going nuts
over the price. When I bought a batch of 25 of the optical encoders they
cost $22 each. The jag controllers were $10, the box 3.50, switch $3.30,
parts for the pcb that makes the optical rotary work with the jag $11.75,
I think the knobs were about $2, I can't remember how much the wire
was. Plus tax and shipping on all of the above of course.
Then it took a really long time to make all the boxes by hand.
I sold those at $75 each shipped. As far as I know, I'm still running a
deficit on this project until I sell at least 2 of the last 5.
Actually there's quite a lot of room inside the jag controllers. Most of it
is empty space. I opened up newer one and there's enough room to get
everything in there, even the switch.
Tempest in the arcade was right handed, so I made controllers that were
right handed. That's all.
