You could probably buy a Filco, Ducky, etc. tenkeyless or wait for the Leopolds on EK (if they ever release) and you will be very happy with what you get.
Only problem is that they do not come with black on black keycaps.
Maybe you can check out the group thread and hop in on the either 7bits Round III GB or imsto's KB GB.
Another thing is... about the HHKB, 86U and 87U, the Topre switches feel totally different compared to Cherry switches.
Should do some research before you buy, maybe save up for the HHKB or 86U

87U is not readily available anymore outside of Korea and super expensive to get one.
The differences I know of between it and the 86U is that the 87U has a numpad built in, lighted Caps Lock and Ctrl, and the additonal Winkey.
Personally, I started off with buckling springs, then Cherry MX Brown and Blue, and finally tried the Topre switches.
This resulted in me selling my Cherry MX keyboards
