I've had good luck with Systech Terminal Servers on eBay.  I've bought 
five of them for use at home and work and none of them have had any 
problems.  Two port ones are around $20 and four port ones are around 
$50.  Some of them support RS-485.  Make sure they come with the power 
supply. The supply is readily available, but why spend another $20? When 
configuring, you have to set them up as "Reverse Telnet".  The only 
issue we've had is if the controlling program crashes, the Systech 
doesn't close the serial port.  This blocks any new connections.

At work, before we started buying the Systech boxes we bought VLinx 
ESP211's from B&B Electronics.  Pricey, but they work well.  They also 
support RS-485.
