For those starting out, i can heartily recommend the Gillette King C Gillette razor. It a solid, well made version of the Muhle 89 and it comes with 5 of the excellent (tho very sharp) KCG blades. It has an RRP of £20, but is often half that price.
I have found the KCG razor works well with any blade and i personally think it shaves a little "better" than my EJ89.
Anything Proraso is cheap and good. Palmolive shave cream if you can find it.
Post shave, the Nivea Sensitive Balm (it’s often reduced in Supermarkets to around £4 a bottle) is a terrific balm for settling skin and remoisturizing post shave. I also keep a bottle of simple distilled Witch Hazel as a splash to use before the balm and it works well.
