You need a razor and a strop minimum.

I'd try to go under 100 bucks on a new razor and get a good quality strop. Package deals can be found at site sponsors.

I highly recommend a brush and soap. That said you can shave just fine with high quality shave gel like aveeno.

Once you get the hang of things and see if you like the hobby. You can upgrade the razor. Your first strop will take some damage. So it's not worth getting a top line strop at first. You just need a good quality strop from a reputable vendor to start.
