Being inspired here on this thread with the LED mods I have just finished LEDun (LED underneath) my Swords of Furry.
WOW, it now looks better than a new machine and the colours are so vibrant I am addicted.
I can not believe the clarity and sharpness this has made, never mind the drop in electrical power and heat.
The back glass I put in wide angle blue LEDs except for all parts that have a red display which were replaced with (obviously) red LEDs, I have got to say this looks a million.
Also noted is that the LED lights flash at a much higher speed where the machine is more interactive.
Worth every $ spent.
