Just wanted to second the suggestion for rhing. I recently bought a modded PS1 from him and he was extremely helpful and took great pains to ensure that I was getting the best quality for my money. This entailed redoing the mods on a new second player before he sent it to me as the first one he worked on had laser issues. I have put in the Power Punch C7 cord and an Isoclean fuse as per his recommendations and the player sounds phenomenal and its not even fully burned in yet.
