Roughly how much do you make per year? I'm especially interested in self employed consultants. I'm trying to figure how just how underpaid I am. 
I basically define systems admins the same way salary.com does:
Systems Administrator
Installs new software releases, system upgrades, evaluates and installs patches and resolves software related problems. Performs system backups and recovery. Maintains data files and monitors system configuration to ensure data integrity. May require a bachelor's degree in a related area with at least 2 years of experience in the field or in a related area. Has knowledge of commonly-used concepts, practices, and procedures within a particular field. Relies on instructions and pre-established guidelines to perform the functions of the job. Works under immediate supervision. Primary job functions do not typically require exercising independent judgment. Typically reports to a project leader or manager.
RDU area median is $58,593. Which becomes $81,714 after benifits/bonuses are added.
