How do you compare product/price?

[qhoc0011]

Hi all,
I wonder if there is a fast way to shop and compare product/price for
electronic components. For right now, I have to search for the product
category like capacitor and pick out some of familiar name. I then have
to read the spec to find out which one is the best. After I collect a
set of best items, I have to compare the price. This takes me a long
time. I wonder if there is a better way to do this. Is there something
like Cnet where we can get some deep evaluation without doing it
manually?

Thanks.
