imre,
I don't think anyone wants to unnecessarily lose components to "dirty power" but I'm not in line with you financial assessment of costs.
" How expensive is that single 42" plasma in the living room? $12K? Mine is new and was < $2000. Those TV Monitors continue to drop in price faster than MM and JDUB can say "taco de pescado".
Computers ?? They are so dirt cheap now that it is depressing. Just bought some upgraded Monitors for < $300 each...
I think the priority would be the house batteries. Not only from a cost standpoint but from the sheer hassle of replacement.
