I am a college student in IT that fixes computers, and, a lot of the time, a client will want me to reinstall a program from a nearly-mutilated disk. I needed something not only inexpensive -initially-, but with inexpensive upkeep and supplies. After a great deal of research, I stumbled upon the JFJ Easy Pro (I had been leaning toward a discgotech).
When I first bought the product and was waiting impatiently for its arrival, I read some more reviews on the JFJ machine. Apparently, there are two versions of the machine: one with a glass-like plastic top, and one with a lighter plastic. I called the company and asked them several questions:
1.) If I get the product with the top made of "lighter" plastic, can I get the new lid?
-- yes, but you have to send it off and spend about 50 dollars for the piece and labor.
2.) I have heard that, after thousands of repairs, the plastic cap that holds the disc while it spins will eventually strip on the metal screw...
-- no problem. The company will usually just send you one free of charge if that's all you need
Basically, whatever future parts you need, you can get a repair kit inexpensively...even after the warranty ends. That's something very important to me.
When you get it out of the box (mine was the new model with the better lid. I bought before Xmas 2008), you can tell it's a well-made product. This thing is built like a bomb shelter, no joke. And, unlike a previous poster suggested, there is no learning curve. The idea is to choose the least-drastic method for the disc at hand. For example, if it's a minor scratch, don't use the sand paper.
If you do use the coarse sand paper, you follow it with the fine, then the white and blue solutions in that order. You simply work your way down the grit level. It also includes a glossy instruction booklet. Better yet, there are vids on youtube (I'll also be posting). If you can work a microwave, you can work this machine. If you can screw this up, you shouldn't be allowed to leave your house without your helmet. That's really all I can say.
The only con is that it won't make hot cocoa for me when I come home from class, I guess. This really was a solid investment, and I hope you find my review useful.
