Welcome to SRP. I'd go for the cheapest brand spanking new Dovo razor/strop set that SRD, Classic or Vintage sells. You're going to need a strop and if you get the entry level dovo it will do the job. Later if you find straight razor shaving is your thing you'll want to add at least one razor to alternate between two, or for a back up. At that point I would go for the aesthetics and get something fancier.
