Sometimes I get suckered into buying from a vendor I've never heard of simply because they have the lowest price I can find....Time and time again though I realize that 90% of them are inferior to Newegg, who I go to for most computer hardware I buy. I would highly suggest Newegg... don't get suckered by some places rock bottom price on one specific item.
Here are some vendors I will never use (again):
www.tcwo.com (don't email confirmation of shipment until days after your order... took 1 1/2 weeks to get item)
www.atacom.com (charged restocking fee on a DOA board that I had RMA'd...would not crossship, had to reorder item)
www.ubid.com (will rape you on shipping charges... way too many people overbid on items)
www.pcprogress.com (average prices, decent selection... but ONE guy answers phone for tech support.. line was busy for hours)
www.tccomputers.com (those prices are a joke right?)
well I could go on but I really haven't wasted my time with too many vendors, everytime I try someone other than Newegg I find out why I go through Newegg in the first place. Sorry I know I sound like a commercial... and Newegg is not perfect, but they're about as good as I can imagine an online vendor being.
