even at $50 I couldn't call it a good deal. It's not really usable, so it's all about either collecting or stripping for parts.
At 80+ (70+shipping) it's a significantly poorer deal.
This is definitely for the sucker who will fall for anything 'new' or 'cherry doubleshot'.
It's certainly a unique piece with an interesting history at least, unlike other boards on the market today.
There are way too many vintage keyboard on the market now with weird layouts. If you don't exercise fiscal discipline, you'll wind up collecting everything under the sun.
When I was in my tens (around ten years old) I collected transformers. In my teens I collected Casio gadget watches. In my late teens I almost started on Soviet Bloc stuff, until I forced myself to give up over-attachment to material things.
Now I don't regret it. $50 or $70 or $7000 may be cheap to a collector, but I don't see the point of amassing a collection of 1000 weird looking keyboards that you can never use. If you can use it, you can make it yours.
I use a Model F XT very often despite its weird layout, so I am pleased to say it's truly mine. I also own a TG3 Police keyboard but never use it. I know I own it, but I cannot actually tell you where it is because I can't remember. Is that mine? It's out of sight, out of mind. If a thief swiped it from my house I might not know for years because that keyboard is not in my rotation list.
So my question to those who think $70 is still cheap is this: if a thief broke into your house and stole your weirdo keyboard, would you actually miss it? If you won't even notice it gone, I would say even $7 is too much to pay for that keyboard.
