A used Heavenly Sword off E-bay a few months AFTER I bought my PS3 for about $37.
My neighbor and I picked up 60GB PS3s on New Year's Day in 2007, so a few months after launch. I'd gotten my first PS2 only the year before and like most people at the time, I had a standard definition TV.
So I didn't play PS3 games other than the PSN demos like Genji because I was busy playing PS2 games like God of War and Shadow of the Colossus in standard def.
When we got a HDTV later that year, life changed, and the PS3 purchases took off: Motorstorm, Genji, and Stranglehold (all used).
