I don't see a picture or link. I think I had that, or one very like it. Mine was horrible, when the foam breaks down, the board is worthless.

   don't know if this one is really mechanical, at least the keycaps are in good shape (seems to be sturdy, PBT?).

Extremely nice rubber dome, at least mine is. Separate RD pieces on PCB, sliders, Cherry-compatible keycaps (lasered lettering). I'd have to take it out of the closet to find out if it's not ABS, though.

Awesome, I was afraid of this one. 30 bucks for at least 104 good quality keycaps is okay ...
Thanks by the info davkol !

I have the BTC-5100C that I disassembled. Really high quality rubber dome. Feels close to a topre, but not nearly as smooth and minus the 'thock'.

But still, not too bad.

Mine is capacitive foam and foil. Springs, not domes. The foam is still in oddly great shape and feels okay for a linear board. The rest of the board looks trashed though. All yellowed and sharpied.

A dome with PCB??? Wow, didn't saw this setup before.
Two types of sliders and two types of keycaps, removable dome, hmmmmmmmm.

Mine is bigger tough (mea culpa, I started the topic asking about the BTC-5369 but at the time I was trying to bid this auction was already closed - then I got the BTC-5139).

I'll have to wait so so 1 month in order to put my hands on this keyboard but as soon as it arrives I'll open it and I will post some pictures here.

I got it to use it's parts somehow but right now I'm not sure that I will have the balls to exterminate him.

Amazing pictures Bro Caps!
thanks by your attention

There is also higher quality version of some BTC 5100 series foam and foil or later individual domes over PCB with doubleshots. Thier doubleshots are not too bad quality and have same profile as SP DCS so it is not too hard to fill in the incompatible ones like the bigass enter, 1.25 esc, bottom row etc. as needed.
