Is there a Thunderbolt to Component Video cable / adapter for the new iMac?

Hello!

My church is looking to purchase a new iMac to run our presentation software.

We currently have a PC that has a graphics card which has a component-out cable. We connect that to a component video distribution amplifer to distribute to several HDTVs and a projector.

Is there a way to connect the iMac to a component video (Y, Pb, Pr or Red blue Green) input?

I understand that DVI is digital and Component is analog, but has anyone found a device, cable, and/or adapter that will do the job?

Thanks,

Randy
