I actually have a TrendNet TPE-S44 8 port switch (4 ports are PoE ports) for sale. I used it for a month. I got the box and manual. It's in mint condition. I think I paid $65 for it. I'll let it go for $45 shipped.
Switches are cheap. Whenever I buy a new PC, I get given switches for free. I am pretty sure that you can get a cheap 100MB switch for less then $30. And they are all generally of good quality these days.
EDIT: Though the good thing about getting something from Tommy, is that you know it is going to work for sure. And Tommy does not buy crappy stuff.
