I spend the majority of my life using these bits so I buy quality.
The value proposition for me doesn't really exist enough to spend out-of-pocket though. Mostly due to not reaping the benefits from increased efficiency.
If that is a big ticket item I would wonder if they are in serious trouble or it's just a shitty place to work for. A managers response to a request like that should be "here's the corporate card" or "submit the receipt for reimbursement"
The guy said "$150 for a keyboard and mouse of someone's choice, amortized over a year or two, is a tiny price to pay to keep our people happy."
I ended up with a Das 4C board at work (with browns) and a custom double-shot keycap set (bought out of my own pocket).

Tires
Boots
Climbing gear
And then I got into hammocking, and nothing seems to beat my first, a Bear Butt I got for 50$. Seems the more expensive they get, they lose out on just being big nice expansive hammocks with silky smooth material. So not a hard rule I guess!
