Hi,
While spares for Motorola are readily available from any dealer, Sepura is another beast.
You can buy batteries, keypad mats, keypad bezels, accessory port cover but that's about it.
At least what I've been able to figure out, the only way to replace the button that are fused to the case (power) - is to FLATRATE the radio for something around EUR230. That's without tax.
The best part is, the two buttons above the screen get worn through and they can't be replaced without replacing the case.

For business use, sure. For hammy use? no.

Has anyone been able to source new front housings for these? bottom connectors or rotary encoders for that matter?
Removing the knob usually makes the shaft break loose from the encoder - not the knob itself.
