AC adapters for laptop from GetPartsOnline.com

I wanted two extra AC adapters for an HP Pavilion dv5210us laptop computer. HP and all the usual places wanted around $70-80. But a Google search for the part number turned up GetPartsOnline.com, which has genuine HP adapters in stock for about $32. The original adapter was a 65W, and the one they actually shipped me is a 90W. This is perfectly fine because it uses the same voltage and connector; it’s just capable of supplying more current, which the laptop doesn’t actually need.
The next time I need laptop accessories, I’ll definitely check their web site.
