PS2 problems

[ps2bud]

I'm having problems with my ps2 giving me a disc read error. The unit has gotten slower in the last several months at startup, taking it forever to load. This last week it started to freeze during gameplay and you had to restart it, now it will not read at all. I was interested in getting my ps2 inspected by someone recommended by this site and possibly having it installed with some mods because I have 2 young boys that play the system and I don't know if they have messed something up or what. thanks for any help!
