Do you think it is old-fashioned to buy PS2 (Playstation 2) now?

I have sold my PS2 4 years ago…. There are so many PS2 games that I want to play. I would like to buy PS3 but the BD price is very expensive. What do you think about if I buy PS2 now? Do you think it is old-fashioned already? But PS2 production still continues, right? Thanks
