I looked her up on Allbreedpedigree as well because you never mentioned her age. First thing that jumps out at me is how downhill she is, do you every have problems with saddles riding up on her withers? I didn't want to say anything till I found out her age because if she was a baby then it could even out, but I don't think I would breed her either.
If you want a good horse with nice lines come out to New Mexico/Texas, no one can afford to feed their horses in the winter becuase Texas/Arizona/New Mexico are in a drought. So if you wait till December you could pick up a horse with good blood lines for as little as $1000(depending on hay situation) I bought my Filly with 10 rides(nice and green) for $1400 with a free breeding to my choice of a race bred Stud or a performance bred Stud. She is Impressive/Doc Bar/Poco Bueno as well on top and bottom but her mother is further down the line than her father.
Check her out, great lines and Color to boot! APHA Cremello Filly
You have to look hard but you can find good deals. :)
Also I have bred a few mares in my time and as long as they are breeding sound I have never spend more than the vet visits and Breeding fees on a colt. I understand that there are things that my come up unexpectedly but I could never see forking out $1800 before a colt hits the ground. IMHO.
