IPv4 /24 Broker or no broker

[TimJ <nanog () authcom com>]

Just looking for info. I know there are a lot of brokers, but is that a 
good (easy and quick) way to sell a /24 ?  We're renumbering and plan to 
free up a /24. My boss is asking how much we could roughly expect to get 
for it, and the fastest/easiest way to 'sell' the block. It's a single 
/24, in the ARIN region (not part of a larger allocation).

Suggestions?
