@zanna86 Thanks for the complements
Every once is a while a v1,v2,v3 will come along that hasnt been used to much and will still have a good laser. However the majority of the time when these old versions show up, I like you also see worn out lasers in them and they need replacing.
As for a good source for lasers Rich from
www.richspsxparts.com is an A1 place for that. He is in the USA but I believe he ships world wide. Contact him he will set you up.
