Reaper miniatures has just added a free copy of the Swords & Wizardry Complete Rulebook pdf as part of the $2,840,000 stretch goal. If that goal is hit, it means something like 10,000 people will get copies of the rules.
Incidentally, if you haven't looked at the Reaper kickstarter, it's pretty unbelievable what you get for $100 at this point.
