So who makes quality PSUs for the budget gamer?

That is a tough call w/o knowing any specs or anything, here is a list of the cheapest ones I have used in the last year of builds, price ascending

SPARKLE ATX-350PN-B204 350W $34 shipped @ ewiz
HIPRO HP-E4009F5WR 400W $37 shipped @ newegg
SPARKLE ATX-400PN-B204 400W $42 shipped @ ewiz
HIPRO TOP-500P5 500W $44 shipped @ newegg
XClio 450BL 450W $47 shipped @ newegg
FSP Group SAGA AX450-PN 450W $58 shipped @ directron
SeaSonic S12-330 $63 shipped @ newegg
ePOWER ZU-550W EPS12V 550W $63 shipped @ newegg
 
Well if you never upgrade any of the 450w+ units should do, I do prefer the fsp ax450 over the xclio 450bl, but if you are considering upgrades in the near future the zu550 is only a few bux more and gives you a lot of headroom.

The 350w and 400w units I used in office/web-surfers, the S12-330 is a great choice for a PVR or basic 24x7 system - not sure if I would use them in modern dual-core game rigs since it limits your options.
