I'm looking for a switch and budget is my main concern. I want as much bandwidth add I can get, but I can't afford 10g upgrades this year so I'm looking for gigabit speeds. I think 16 ports would be ideal but more are always good. I'd prefer a rackmount, but it's not required. I don't need any management features outside of vlans, but I highly favor any equipment where I can learn new job skills. Because of the learning potential, I'd like an enterprise grade switch that's old enough to be cheap and easy to find on eBay. Any suggestions of what to look for?
