If it's clean enough I don't see why not, there have been plenty of boards go over $500, all you need are 2 people who really want that specific one. Truly NIB for a pre 1986 keyboard is pretty dang rare.
thanks men, I was kind of checking about since I found 3 NIB for $160 each, thought I buy all 3, keep one for collection and sell 2 of them, turns out they just canceled my order someone did typo mistake from the warehouse when they were doing the inventory. I really wanted one, although I have a chance of obtaining the 83 key one for $75 used, but in original box + excelent condition, but not sure if its worth that much as collectible since its not really friendly useable even after doing the teensy, the layout of the keys is somewhat weird.
Whats really weird last night the sold 2 XT's NIB for $250+ each on ebay and I have seen them go for $300 or more when they are NIB....
Any ways at least I settled with something what I believe its really nice, its not NIB, but its somewhat rare its in excelent condition and comes with original packaging. Got it for $65 :-) and will join my other square logo that has the LED overlay and this one does not, and I really badly wanted this one since I dont have it in my collection.... Here are the pics of whats coming my way!!!!!!
