Buffalo BS-MP2008 Layer 2 MultiGigabit Switch 8 Ports. I tested it for basic function and it worked. I'm willing to run tests on it, if you'd like to describe what you need. I'm also going to be willing to partially refund you if there's a small problem or fully refund if there's a full problem - I have a long sellers history and will work with you. It's a bit loud to run, as all pro equipment is, but I don't think it's unusually so.
