safety razors

I browsed r/frugal and saw some archived posts on safety razors - looking for more input from the ladies that use them (or men who have found great products). Have they been a worthwhile investment for you? Where have you found the best quality razors for the price (new/used)? What brands seem to be best? Any tips/tricks? What shaving soap/oil works best? I've been looking into trying these, and moving away from the usual disposable stuff.

And, the important question, ladies - have you managed to shave more than just your legs without causing a bloodbath?
