What would a brand new big stick sell for

Just wondering, if you could find one, what sort of price would you expect to pay for a brand new, unused, boxed old style big stick controller.

Someone was selling them on ebay a few years back at $200 which I thought expensive.

£75 or so I've seen a couple go for.

The seller was raretro-game-collector. He had about ten units, I contacted him to see if he'd negotiate price but he wouldn't budge. $200 seems a lot. Maybe $150 when the dollar/pound rate was better.
