Hi,
Recently I need to find pricing of different hardware, and hence I have search a lot as they are not so common hardware devices I am looking for. After many research I got only two sites where I can check current price and specification of hardware.
Please take a look at these site, Though I never bought anything, but they give good idea of what hardware means what 🙂
