Where's a good place to shop for laptop batteries?

[HelloWorl]

Looking for a Dell Vostro 1500 battery for my mom, but every website I've seen so far has looked pretty shady. Is there anywhere that's reputable so that my mom doesn't get ripped off?

Thanks

Ebay from a 99% or better seller with thousands and thousands of transactions.
