If you can find a afm very cheep then maybe worth doing a full restoration rather than buying one already restored
i have restored many afm to supermint standard then when i come to sell i have spent so much money to bring it up to supermint i make very little or no profit max £300 witch for the amount of time put in is nothing but if you enjoy restoring them and are going to keep it then thats up to you
here is an example of cost of restoring one
afm to buy as is £2500
playfield £750
cab art £250
ramps £250 all 3
plastics £120
bill ung led kit a must £160
new martions
new mother ship plastics
new flipper bulbs rubbers ect ect
all metal parts polished or re plated
cab to sand fill and repair new side rails
new dm
the price is now over what you could buy a very nice restored afm for
