Go slowly...you only have one face
Well, here I am more than 2 years into this and still consider myself a beginner. The best advice I can think to offer is to go slowly...
read, watch videos, buy a shave ready razor or two, a decent strop with replaceable leather (taken my word), work hard on learning your face...beard direction, etc, work equally hard on lather, stropping and stretching, and then go as slowly as you need to on shaving. It takes time to learn.
Screw up any one of the things I've mentioned, and you'll get a bad shave (take my word again) and generally speaking stay away from "cheap (eBay, etc.)" until you know more. On the other hand soap or brushes or mugs don't need to be expensive, just proven (read more posts about what you're considering).
It will get better, just keep at it... Listening and learning. Members here here with lots of posts can be trusted to tell you the truth. Watch for them in the forum, in the classifieds , etc., and you'll be fine
Oh, and one more thing, there is no "best" anything...everybody has their own face, their own technique, their own water and their own opinion. Just buy decent, well regarded stuff. It will work for you.
have fun!
