Imo, DE shaving is the way to go. Most recommend starting with something like an Edwin Jagger or Merker razor. Most vintage Gillettes are good and clean up nice and the adjustable ones are sought after, particularly the ones called a 'fatboy'. These are available on Ebay and imo worth the investment. Initial start up costs can be very low or you can get carried away and end up buying several razors (a syndrome referred to as Razor Acquisition Disorder ;) You can also order a cheap chinese razor and they work well too.
Blades are mostly personal preference and you need to take into consideration your facial hair type, skin type, and aggressiveness of the razor. Most recommend a 'sampler' pack of blades ordered online and once you find ones you like, then you can order more reasonably by the 100 pack from online sites.
For the full experience it is recommended to use a badger brush and creams and soaps as opposed to shaving foams in a can, but there really are no rules that say you have to. You can also buy a bristle brush for less money. You don't have to spend an arm and a leg on these things for good results, but again one can get carried away.
There are lots of forums that discuss the benefits and offer advice on de shaving so google is your friend. It does take a little longer and at least 2 passes but turns a boring ritual into something enjoyable. You can also be a bit too nervous at first and that will pass as you develop a good technique.
