Hi there. I've actually made a few Tron costumes now as I love to work with EL tape/wire. The Kevin Flynn discs are rare as Spinmasters only produced a small run of them in comparison to all the others. It's worth keeping an eye on amazon as there are a few shops that sell new disks and recently went from sold out to due in stock just recently. The alternative is to get a Sam disc, tape over the inner ring and blade, then spray an undercoat in white, then give it two coats of White PlastiDip spray. This will give it the same texture the disc had before the White undercoat. You will still have a blue c ring and blade but short of recasting some clear parts it'll be closer to what your after. EL panels is the way to for the more complex shapes but make shure they are the cuttable ones with tabs all the way round. As long as your shape has one of each tab your good to go. I would go with the 12v power pack. Coolneon.com is a good start and they will help answer any questions you might have. I put mine in the disc holder as even the 12v inverter and batteries can fit inside ok. I still added a bit of padding to help secure them a bit. If the budget fits it might be worth checking out Soulinetia on this site as he has full disk mod kits or pre made discs of all colors. He's a wanted man for these discs mind, so the waiting list is pretty heavy. Would love to see some progress pics of your build. Are you going to put some up?
