On paper I like Vinnie the best but I would never recommend a horse without seeing it in the flesh - and you should also get a PPE - even if the horse is 'free'.
Since they're all coming with 'baggage' from past experiences and are unridden then I'm assuming you've either got a good trainer on hand or you've got real time experience of handling these sort of horses.
A cheap horse like this can end up costing you more in the long term that a good ready made one
Since they are all good doers don't forget they will be high risk laminitis horses which is going to mean restricting grazing in the late spring through to late autumn.
The first two are from a mustang foundation. They were rescued a year ago and have been in training for a year to rehabilitate them. They are very sweet. I don't know if you have mustangs - but the gene for laminitis is incredibly rare, as mustangs will laminitis die off in the wild and therefore do not further along the gene. Very few mustangs EVER end up unsound. They have been grazing their entire life, since caught from the wild. These ones have amazing feet, as the mustang foundation they are with (in NH) has a barefoot specialist on site, as well as a dentist and a vet.
The first two are available for $1000., and if I want to continue training with them on the farm after purchase, it is $1800 to work with them three times a week for 4 weeks and they nearly guarantee a trail ready 'stang. They have been doing this for a few years and have placed many horses. They were also in the movie "Wild Horse, Wild Ride," the documentary. (The farm was, not the horses for adoption).
The last one has no abuse in his past whatsoever. I am not sure what the woman is asking at this point.
