for me crash bandicoot doesnt even rank

Yes, they are on PSN together with some other PSOnes - I think the section is called "Lost Treasures" or something like that. I think the price is something like 5 euros or so.

I loved CB even though I generally don't like those kinds of games (do something, screw it up, do it again and again and again...).

well sony has hidden them damn well on the psn here

Select "All Games" on the left tab and then PS One Classics. They should be there, along with other PS1 games.

ah sooo
its damn near impossible on the ps3 though
the store ha sgotten an ugly overhaul everything is sluggish its a complete nightmare

Yes and with every update the store seems to get worse. Sony really should hire decent designers to redesign PSN.

i buy my psn games via the pc and shunt them via my account to download them on my ps3
its almost impossible otherwise

I remember playing Crash Bandicoot on PlayStation 1.It was my fondest memory of my childhood.Also that "woah" death sound became very famous as a meme even in many compilations.
