The first is to downhill conformation wise. The second looks aggressive, and thick. Kinda like me wants to crush you O_o The third looks like a gelding with no rump D:
Keep looking...theres really a lot of good, quality studs that are pretty cheap. Sure, most to all haven't competed, but still breed nice foals.

He's a lower priced, non-competing stud, but he has an incredibly docile personality and good conformation. He throws in some beautiful, flashy gaits to. Another plus is that you get a huge variety of colors (black and white, chestnut, flaxen, bay, black, palomino...) and often lots of hair 8D
I got the chance to meet a MFT x Arab filly of his. Black and white, abandoned by her mother. She had an incredible conformation and was just full of spunk.
You don't necessarily a fancy stud to produce a fancy foal. Get a good mare with a great conformation and temperament, then find a stud who can match it or better. If given the choice, I would breed my mare to Dusty's who's never been in the ring, over another that's won ribbons.
