Well, I don't know about free being the best.
Or this script being the best.
But it is free:
osDate - Free, open-source dating system.
i'm looking for the best free dating site script, can you suggest me some of it?
i found one and it says free yet when i saw the page, its for sale and i can't afford it
i probably end up using osDate.
but i'm still looking for something sophisticated other than that
