<< I ran into a serious problem with a 250w Antec >>
I think Antec is the more over rated hardware company on this forum. I bought an Antec case & PS for $89 (!) for a friend who lives in Mexico because Antec has a great reputation. Eight months later the PS exploded in his face, straying the inside of his case with acid and singing his beard, blowing out his surge supressor and tripping every circuit braker in the house. The system is more stable with some no name ATX PS he bought in Guanajuato.
I bought a couple of KS282s for $50 each delivered from Onvia and while they've given decent service, they don't have a power switch on the PS itself. Virtually every other cheap POS PS I've ever seen has a power switch on it. I have to unplug the sucker to feel half way secure when working inside the box. Not a huge deal, but not so wonderful either.
