wow that's a lot of loot
This is the machine I bought; a disc-go-devil. It works great and was only $1000.
By the way that Devil machines are also some I'd consider not too good but it seems there are different models and the ones from segamer seems to be their topline.
The machines I mean are these ones ->
http://www.discchek.com/ecoautosmart.htmlInsanely pricy but well worth it. Almost 100% flat surface removal. Different pads for automatic removal of very little to very much surface. Wet polishing/grinding process - which means next to no heat generation.
I've used this machines for years and have to say they make even the most scratched disc look like it had never any scratch. Still too deep scratches are difficult to remove and need quite a few runs on level 5.
They can even repair scratched Blurays.
The only downside is that even on this high end machines PS1 black discs look a bit "sanded" except if you do several finishing runs.
The whole different pads and liquids you need also don't come cheap! So all in all not feasible for a private person. Luckily I know a game shop who has one.
