So.... Going to keep this short. I really love r20 and the collaboration with WotC. But the srd has a bit of the Swiss cheese brain going on (quantum leap fans in here?) Basic stuff like bard features and paladin smite spells are flat out missing. So... I would pay good money to have a proper PHB. I think 20 -25 USD would be very fair. I am all for paying for someone's time and effort, this would be no different.
