How many people buy the consoles depends on a lot of things, particularly the time of year and value of the console in question. prices at this time of year are slightly higher than normal because of christmas.
for example:
The average cost of a good quality NES system with two controllers, one game, and all the original cables is about 100 AUD, provided it is in good cosmetic condition. Around christmas the value of the same console can increase to 110 because there is more demand.
