Hey, first, how much money are you looking to spend? All you'd need is an interface, some kind of software, a preamp, and a dynamic microphone. There's plenty of software out there that are cheap programs that will probably be enough for him, the best dynamic for the $$ is the sm-57, i don't think anyone would disagree with that, and a good cheap pre is the VTB-1, which runs around $50-60 used if you're willing to shop around. The interface, well, there's plenty that are dirt cheap if you look on musiciansfriend, but my opinion is that if you get the cheap cheap ones, you're just wasting your money, and are better off dishing out the $100 to get a used Delta 44. Which reminds me, is he using a laptop? the delta won't work with it because you need to install a piece of hardware, so you'd have to go another route, probably through a firewire port. Anyways, hope this helps!
