I've got two questions again today (I ask too many, don't I? lol)
1.) What choices do I have for TKL boards with Cherry switches?
2.) When desoldering a backlit keyboard do I also have to desolder the LEDS? If so how much time will this add to the process?
There are a ton of options for TKL boards. The general ones people gravitate towards are Ducky Pro TKL or Shine II TKL, Cooler Master QFRs, and the Keycool 87. If you're willing to go smaller form factors, you've got keyboards like the Poker 2, KBTalking Pure, Deck 82, Keycool 84, Tex Beetle, Poker, GH60, etc.
Yes, you have to desolder the LEDs. How much time depends on the number of LEDs. Assuming every key is backlit, it will double your time since you will be desoldering the two switch legs and the two LED legs. But once you have them desoldered, you can get a modified plate and dremel the switch top and you'll never have to worry about desoldering LEDs again.
