Amiga CD32

Hey after talking to one of my friends i found out that he had an old Amiga 32 (which i had never heard of) and that it wasnt working. i offered him $20AUD for it and took it home and cleaned it up and now it works fine. i have 1 controller and about 15 games, and i'm just wondering how much this would be worth cause i have been told it is worth a bit.
Here's an NTSC version that is boxed that sold on eBay:

$140 USD

although here's a couple others that are probably more in your condition:

worth a bit more than you paid
