Mike has SS1Ks for pretty freaking cheap.  He can ship them for peanuts,
too.  I don't know how cost effective they are to run though.  I can
barely keep 4xSS2s 1xSS20 and 1xU1 powered up here without blowing fuses
(yep, those screw in fuses are still in use in my house.  Augh!)

I think that design is a bit over thought for a home network.  You can
get away with making things a bit simpler, at the cost of expansion not
being so great.
