if your going to do and insist on gigabit at home, i see no need for it, but if you do
get a real gigabit switch, not a junker $100 layer 2 switch
the cheapest real gigabit switch i can find from cisco is the 3508
its an 8 port GBIC switch so you need to buy base T copper gbics for it as well
you can buy them in 4 packs form ebay as well
NEW 4-Pack WS-G5483 1000Base-T GBIC Module 1-Yr WARRNTY
so get 2 packs of those and your set
the 3508 will do true gigabit switching, jumbo frames, vlans, management, snmp
and a stack of other cool tricks, ether channel, spanning tree
also if you find its noisey, you can replace the fans with 5v fans instead of 12v fans (i did this to mine)
gbics for it

failing that check out some dell gigabit switches they usually go cheap as no one wants them
and should be fine for home
