Does anyone have experience with the durability of Topre's laser etched light gold on black PBT keycaps? I've scoured the internets, but my google-fu has failed me. The Deskthority Topre page mentions that they're not as durable as the dye sub version, but it doesn't actually say by how much.
I use a Topre 105UB variable at work, and it has the black on black PBT keycaps. I'm considering getting another Topre (45g uniform) for use at home, and currently KeyboardCo is the only source for Topres with a Finnish/Swedish layout. Unfortunately, they only have the 105 with the laser etched keycaps. I've had a bad experience before with laser etched ABS that started to wear off within months on my old Matias Quiet Pro. Is lasered PBT any better? My understanding is that Topre doesn't use any filling colour with the caps, the gold being a byproduct of the engraving process.
...input, anyone? Thanks!
