Audience Screen - Your Methods?

[dag0620]

One of my latest projects of things to try to tackle is getting together a successful audience screen for our teams off-season event, without having to get a video production service to do it.

I've got most of this figured out, and understand the concept (FMS Audience Program spits out the screen with chroma key, and chroma-keying software is used for the layover, etc.). Now theres several ways to go about this to get the end product, and thats what I'm here for.

I want to ask teams/individuals who've done audience screen before what they feel works best in a video rig for an FRC competition. The info I want to know is what hardware and software you use to accomplish this task, any tips or tricks you may have, and the aprox. price point it costs you to accomplish this.

Any help would be great!
