So after a year of owning a game store, searching for a way to fix damaged CDs and wasting a lot of money on resurfacing machines and supplies for them I think I have found the easiest, and most effective way to do it. I always like talking to people on the legacy forums so I will share my find. All you need is:

6inch bench grinder (Got mine at sears.com for $35 with in store pick up)

2 6inch cloth attachments for the grinder (Sears had them but got them at Lowes beforehand for $5 a piece)

1 wax polishing stick, white (Sears again for less than $3.00)

Windex or microfiber towel. Either method works

You can easily get the entire setup for under $80 if you do some browsing.

Scratched CD (Hard to get a good picture of, but totally damaged)

Grinder set up. Make sure there is nothing that can not get some dust on it in the area as the wax will sometimes flake off.

C-Clamps help out with the vibrating

Apply wax stick lightly. If it starts flaking into the area below it then you know you have enough on.

Lightly apply the disc to the pad, HOLD ON TO IT OR IT WILL GO FLYING, left right, left right buffing motion all the way around.

Apply some glass cleaner to the right pad and repeat the buffing process.

Hard to tell but disc is about 95-98% condition afterwards. Could possibly be 100% but it's Scarface for PS2 so I am not putting the extra effort in.

Overall I have fixed GCN Games, and taken the rings out of Xbox 360 games. I haven't really found anything unfixable yet though I am sure it can't remove extremely deep groves, and obviously nothing can fix scratching to the label. Use the wax conservatively or else you have to spend more time taking the wax off. I'll try to answer any questions, good luck!

It's a thing that not enough people understand, items depreciate in value over time (Unless they're rare and very much sought after). When you've bought a game, the longer you own it, the more likely it's going to go down in value. Besides, the value of money itself depreciates over time anyway due to inflation and such, so old games are cheaper now. I can completely understand your rejection of old PS2 games, they're in abundance in most shops I go to, maybe have a notice or something saying certain game trade-ins are "subject to negotiation" or have a cut-off point for certain games. What In tend to see in Used game stores around where I live is a list of games the store is looking to buy off of customers for trading in, usually popular ones or games that the store doesn't have much of, it might get people who look at it to think "I have that game, and I'm pretty much done with it, maybe I should trade it in for a bit of money."ModeDude
