Not much. $25 would be a fair price.
Roughly $25
The slimline came out in September 2004
They should but if your PS2 Slimline won't read PS2 games, then the red laser inside probably burned out. I suggest buying a new one
It depends on how severely damaged the ps2 is, and if it is fixable.
It is not available for the Playstation 2
It may depend on what you want to do with it, but in general it does not really matter, except for price/warranty issues. The slimline PlayStation 2 is smaller, quieter, includes an Ethernet port built-in, and is still available brand-new. On the other hand, it has known issues playing some PlayStation games, and lacks a bay for a hard drive, thus Final Fantasy XI cannot be played on it.
well if u have to much stuff saved on it that could be the answer
Almost as much as if you did not trade in a PS2
$20
About $120
Playstation 2 costs arround Rs. 10,000 in Pakistan
You could probably pick it up second hand for about a tenner now.
