Thanks for the compliment. While I usually mod a little and add lighting, I can't take full credit for this one. jefff did most of the light additions before I bought the game from him, and did an awesome job. He added a trough strip, and another strip under the backbox above the rear PF. He also added four spots on the lower PF (above left sling and right stand ups), and another spot up top near Frank. Spots really make all the difference. I added four to my old DE Batman, and it made the PF look so much better. He also put mirror blades in, which help the illumination of the PF a lot.
I added 5 SMD cool white and blue towers under the return lane ball guides, replaced the bulbs in the spots with 4+1 no dome cool white SMD's and some other Flex two-head LED's in a few other places. I also changed a few of the rubbers, and installed orange Convolux plastics on the slings and ball guides. He put the color DMD extender in (which is awesome). The cable crapped out, so I had to play with it for a while. Switching it around helped at first, but ultimately symptoms returned and I had to replace it.
MSF tends to be dark, so I would definitely recommend the trough LED strip, and a few spots. Really brightens the game up.
The head moves on this one, but on my old MSF I had to replace the servo. Not sure if hobby or RC shops have the right part, but they may carry something "somewhat compatible." I think I ordered my servo from Bay Area or Marco, but they didn't have many. I remember because I got the filing cabinet mech for X-Files at the same time, both hard to find parts. I would try to find one if I were you, before you start playing with alternatives or manipulating the game.
