Ask HN: Is there such thing as a “reputable” domain broker?

I'm considering selling what I consider to be a fairly valuable domain name that I've held onto for quite some time.

(Not a squatter! I've tried developing it more than a few times and failed miserably.)

It's 4 characters total, including the TLD, and it spells a catchy english word.

I would prefer to just drop it in the lap of a domain name broker and see if they can find me a decent price for it.

Only problem is, I've never actually come across one.

Every domain broker I've crossed paths with reeks of scam.

Reputable domain broker, are you out there?

Suggestions or general discussion welcome!
