I guess I am the only one that's gone from Arabs to Fox Trotters here.
My first and second horses were Arabians. Loved them to death, wonderful trail horses. Then my next horse was a Paint, then a Mustang, then a Fox Trotter, another Fox Trotter and another Fox Trotter. Current horse is a Fox Trotter.
I never did know how to post (I am just a western trail rider) but I don't miss a hard trot AT ALL. I found with trotting horses I was looking for ways to collect them up when they trotted so they would be smooth. The Fox Trotter I have now goes automatically into smooth.
I can't fathom, honestly, why most everyone doesn't ride gaited horses. I love non-gaited horses too, and would still own one if it was the right horse BUT all things being equal I would definitely choose gaited over non-gaited. I just find them so much fun I giggle! Why wouldn't you want a smooth ride?
Gaited horses are really expensive in Arizona (like $5000-$10000) so I have never out-right purchased an expensive one. I got an exbroodmare once, and she came pregnant so I got a foal and now I have another I got from a friend (actually for free, and she is awesome). But nearly all horses in my price range are non-gaited types. To me, gaited horses are the luxury rides.
PS. Fox Trotters are closer to regular trotting horses than other gaited breeds because the fox trot is a broken (miss-timed) trot. Most other gaited horses do lateral gaits. Keep in mind though that many fox trotters also do lateral gaits and some other gaited breeds also fox trot. So the horse doesn't read his papers.
