For the record Provaris are no longer made, the company closed down years ago. If you want one you will need to look on the second hand market. They pop up regularly on the classified listings on ECF. They come in several finishes. Plain silver polished metal and fancy Zencote finish are both indestructible. They also come with a painted finish which is seriously delicate and doesn't last long.
I'm not as convinced as some folks are about the hardiness of Provaris. I had one where the positive battery contact on the bottom of the board broke off, it was toast. Then I had one where the fire button wouldn't come back up on its own after I pressed it. Took it apart to see what was wrong. They don't have a spring under the button, just a thin silicone dome to push the button back out. Fairly flimsy. The silicone dome on mine had split. I was able to take out the button assembly from the one with the broken contact and got it back in action.
To be fair I've used Provaris daily for 9 years and the first one I got is still working fine.
