Quoted from hocuslocus:

NIB - new
NOB - really nice, but still basically HOU DOC
HOU doc - really nice
Restored - Restored supposedly?
HOU undoc - kind of nice
HOU needs work - This category is stupid
fully shopped - cleaned the glass and replaced a couple of rubbers
partially shopped - the glass got cleaned
Fresh of route - a beater, but at least their honest about it.
used shows wear, but working 100% - not broken, but still needs a lot of work to play right.
Used shows wear, needs work - broken and needs a lot of work
functional minor - broken
functional major - really broken
there are way to many categories, it tends to make things confusing for the buyer as well as the seller.
think it'd be easier if it was 4 or 5 categories. Just my opinion.
NIB - new
HOU - only one owner
Restored - restored
used - 2 or more owners (partial/full shop, partial restore etc.)
broken - broken
then the details with pictures.
