What do you guys do when you need to replace a ps1 or ps2 case? Is there a specific brand or seller that sells these cases in bulk that match the ps1 & ps2 cases exactly?

I spent a good chunk of yesterday trying to find good cheap replacement cases for my used games and bestbuy & oficemax only carry rainbow colored ones, or the super thin kind. So I stopped by my local radio shack to see if they had any clear thick jewel cases for PS1 games and they do, but they have these i.d. numbers printed inside the corners of the case and these weird small circles that kill it for me.
