All of our systems and original boxes are graded based on cosmetic condition, relative to how they came from the factory. Pluses and minuses may be assigned when a system is slightly better or slightly worse than the three grades we offer.
The grades are as follows:
Grade 1: System is as new, with no more than one or two minor blemishes in places not visible when sitting on a desk. Yellowing must be non-existent or barely observable. Grade 1+ is reserved for new/unusued or systems that show no signs of use or any discoloration. Grade 1+ systems cannot be distinguished from factory new systems.
Grade 2: System is very presentable, with few blemishes and/or a little yellowing. Cases have no cracks. White keys may have yellowing on their sides.
Grade 3: System may have cracks on the case, significant blemishes, missing trim pieces that do not affect proper operation, or significant yellowing. White keys are probably fairly yellow. These systems are discounted significantly and intended for people who want a system but don't care that it doesn't look great on a desk.
Ungraded: Non-working parts machines, non-working components, or items that obviously can't be graded (such as cables or disks).
