My suggestion:  go with an Enermax 450 or 550 Watt.  I have the EG-651, the
550 W, 650 W peak model.  Its a very nice PS unit.  Dual fans and fan speed
monitoring.  Cost for the various Enermax supplies;

ENERMAX EG365P-VE(FCA) 350W SWITCHING POWER SUPPLY (AMD RECOMMENDED)  $75.95
ENERMAX EG465P-VE(FMA) 460W POWER SUPPLY (P4 READY)  $99.95
ENERMAX EG651P-VE(FMA) 650W POWER SUPPLY (P4 READY)  $159.95

The other brand I would recommend is Antec.   I have a 300W PS from them.

ANTEC 300 WATTS ATX POWER SUPPLY W/FCC FOR P4 SYSTEM  $43.95
ANTEC 350 WATTS ATX POWER SUPPLY W/FCC  $54.95

I got these prices from Atacom.com, where I tend to get a lot of my stuff.
Local ppl may be more expensive.   You will have to determine whether tax or
shipping is your best bet for pricing,etc...
