Thanks for the opinions. I also own undefeatedfitness.com and was rather getting an appraisal for personal use (don't plan on selling).
I plan to develop a brand named UNDEFEATED and I'm tossing up between the two domains:
undefeated.co
undefeatedfitness.com
Of course the 2nd one is much longer, but I don't know if that's outweighed by the fact that it's a .com over the .co
