Greetings, disctron and welcome to TRON-Sector!
I've never played disc golf myself. As a kid, I often pretended my frisbee was my TRON disc, and I used to see how far I could throw it, but I never played an organized disc golf game or anything.
In terms of getting a TRON-looking disc, you'll probably have to make your own by modifying a basic frisbee or flying disc as they're called generically.
If you do end up making your own TRON disc, make sure to post some before and after photos for us. We love stuff like that!
A couple of threads you may want to hit are:
What's with your name?

Don't forget to PING in every time you have yourself Another dose of TRON
I think you'll enjoy your time here at The Sector
