Good brands according to me include Antec, Thermaltake, OCZ Powerstream, PC Power & Cooling, Fortron FSP & Enermax. I used to use an AntecTruepower PSU before I bought my current one and it was rock solid for the 3 years I used it. It now runs in my Dad's PC with a 2.8 GHz P4 and a 6600GT without any problems.
