Whilst I have never been inspired by Basic Fantasy, it is quite the tried and true OSR system.

New to OSR?
Here are three widely tested systems which offer free PDF rulebooks.
Basic Fantasy Created to be compatible with 3/3.5e, this is fully fleshed out OSE goodness written to be more approachable. Uses ascending armor class. Print options are sold at near cost and are very very inexpensive.
Old School Essentials Basic OSE is the most popular reproduction of the original B/X set. Uses descending armor class. With several different iterations at several different prices, this PDF is free and covers the basics. Enough to get a game going.
White Box : Fantastic Medieval Adventure Game A spiritual successor to Swords & Sorcery White Box. This is the complete OSR experience. Uses descending armor class, but contains alternate status for ascending. Like Basic Fantasy, the print version is under five bucks on amazon.

BFRPG is such a great system. My order for the updated rules and supplements should be arriving today!
I love BFRPG so much. Easily the most played OSR system for me. Maybe there are better systems, but this one is driven 100% by love. My hardback book is just a couple days away!
