Welcome. If you're going to the AOS store I recommend two items of purchase: An adjustable Merkur razor like the Progress, and get a sample of their shaving cream, which is really good stuff. When it's time to try old Gillettes out, among the best are the 'Slim' adjustables, which deliver a superb shave and are worth seeking. As said above, take your time; there's no shortage of DE razor's to try, it's all about earning yourself a good close shave with a minimum of effort.
