I'm looking for a power brick for an HP JetDirect EX Plus external print server. I was given the JetDirect without the power supply, and RadioShack et al don't have a replacement because it requires 13v (weird, I know). People on eBay want $20+ and $10 shipping on one of those, which is exorbitant. Anyone out there got one to spare? PM me or e-mail email@example.com.
