What kits are you seeing? Some are really disposable multi-blade razors that are packaged to appeal to hipsters.
You want single blade. I dunno about a "kit" but Amazon has a bunch of razors from Merkur which are good.
I like the feather brand blades, but Derby might be better to start with.
I use nivea shaving cream from shoppers, I like it a lot more than proraso. Currently running a cheap Omega boar bristle brush, but I have a badger brush as well.
