I'll look around and see what I can dig up. Is ebuyer listed in pounds or american dollars? I' m not familiar with the conversion.
EDIT: nevermind, I see that it is listed in lbs. Thanks. By the way, what are your wattage requirements?
Here is a nice OCZ, the same brand that I myself own. I can testify to it's quality. The only difference between this one and the one that I own is modularity. It is listed at ebuyer for 55 lbs. and free shipping. As I am not sure if this site allows links, I will simply give you the item number. Just go to ebuyer.com and search for product number 127861. Depending on your wattage requirements, this would be a decent one for your budget. Feel free to browse around though, but I would steer away from all but a few manufacturers when it comes to PSUs. Some of the more reputable ones are, for the budget minded, Antec, OCZ, Corsair, Thermaltake. As for the buyer with too much money to blow, there are the top of the line manufacturers such as Tagan and Silverstone, however, these are usually way too expensive for the 'average' buyer. By no means is this a definitive end all, be all list of quality PSU manufacturers, but simply a reference. Good luck and if you have any other questions, just post and I'll do whatever is in my knowledge to help.
