well.... system only (JApanese toploader)... with 1 controller in working condiition (may not be the best cosmetic) would be somewhere between $100-115.
That'd be your best bet... if you are trying to save money. The US systems are hard to come by... and are expensive.
CDZ = the double speed drive (not actual double speed... but more memory and all... IMO the loading is faster too....) runs between $180-275 the latter being in better condition and boxed / complete.
Frontloaders $140-230 ... the latter being 100% complete in nice condition in box.
Welcome to the boards we hope to see you around! We could use more traffic in the Neo Geo CD section.
