If you use a HTPC and extender you definitely want something better than the Monoprice or Linksys. Most 1st and even 2nd generation consumer Gigabit switches are absolute crap. Even worse when you use mixed network devices like a Fast Ethernet based Xbox. You would get better performance from a Fast Ethernet only switch.
Based on as little budget as possible I would recommend the HP J9559A#ABA V1410-8G
