Thanks for this! I use a Perrix 835 and I'm quite happy with it except that the keys are rubbing raw and I need new key caps. But I'm always looking to trade up if possible.
There's a whole world of custom split keyboard options out there that use switches where it's super easy to buy replacement keycaps. You can get keycaps made of PBT which are long-lasting and have a very high "rub" factor so you shouldn't have to worry about rubbing them raw for a very long time.
