Greetings Nicolas & Welcome to SRP.
I just joined here recently and all the fellas have been very helpful with advice. I did a lot of research too before buying a razor and the first thing I learned was stay away from the gold dollar razors! I did see a bunch of people talking about Larry at Whipped Dog Razors and checked his site out. I bought a "site un-seen razor" from him for $43 and he sent me an old shave ready Union Razor Cutlery Co razor which I absolutely enjoy shaving with. I also bought a cheap Van Der Hagen brush, soap, mug and stand for $20 on amazon. Throw the soap in the garbage!!! and keep everything else. Spend $23.99 on amazon for "Baume be" shaving soap it is amazing and lasts a long time. By then you will have the "itch" and will be looking to buy something nice from one of the guys on this site, which I just did last week. Good Luck and have fun!!!
