Much better imo.
Much harder too expecially if you're not sure of exactly what you want and you don't know the artists style etc. Even if you commission some custom stuff I think sites like istockphoto are good to help with ideas + if you've got editing software you can customise vector images yourself.
Did you read through the extended license option on istockphoto? I haven't in detail but I think that allows images to be resold (with some restrictions)
