I know how restless the search can be. I got rid of my first horse as I needed an easier horse, and after I would spend hours on Dreamhorse and Craigslist looking at horses. After months of not finding any to look at, my neighbor took me to look at this green broke reining/trail horse. He was the most hot, unruly horse while saddling up, and definitely wasn't the prettiest out of the pen of 20 horses. But, I took him home.
Try looking in the more unlikely places for a horse of what you want :) Originally I wanted a QH and I ended up with an arabian cross. It's a lot easier to be happy with a horse when you aren't shopping for exacts. Heck, when I bought this horse he was gonna be a western horse, and 6 years later he is an eventer xD
