I don’t have one, but I have a soft spot for a Selectric.
If I could get a PC keyboard that had the same feel, I’d be in heaven. Closest thing I ever had was an OEM PS/2 keyboard.
You can still get the original IBM PC keyboard (but with USB if you prefer that to PS/2):
That is my favorite computer keyboard by far. (I’m currently using a similar, but not identical keyboard).
The very best keyboard I ever used was on an IBM terminal. The keyboard layout was identical to the original Selectric, but the keys themselves didn’t have a decent feel. However, they had a solenoid (essentially, a computer-controlled hammer) that whacked the case with each keystroke. It perfectly emulated the Selectric.
