Thoroughbreds of a Different Color

I'm just starting out in EV racing land - actually I'm totally new to the game as of this month - and am looking for more racing-trained or -trainable Thoroughbreds for future breeding lines that are not chestnut or bay.

If you have any you'd like to rehome for less than $30k, please link! I've been stalking horse search, but keep roaming right out of my budget, and I have pretty terrible luck with the EC.
