I agree with you, K.T., I think it takes someone with a lot of gumption and a very clear steer on what they're after to import a horse unseen. I had some exasperating experiences in the UK trying to source a QH through private ads, and looked seriously at importing - but quickly realised that there was little point importing a western-trained horse when I myself wasn't a western-trained rider. It's not as simple as reading a few articles to convert your English way of riding to match the expectations of a highly trained western horse, whatever the discipline.
Happily, I found that there are a number of Western trainers in the UK, along with a growing band of breeders and websites such as
www.aqha.uk.com to put those interested in the QH in touch with people locally who can help find what you're after. Agreed, QHs are not cheap over here and it's easy to get beguiled at the thought of importing a value horse from US or Europe, as I very nearly did - but I'd have made a grave mistake if I had done so as I would, over a period of a few years, probably have wrecked that horse as I wouldn't probably have invested in the rider training needed to make us a really solid partnership.
But back to the OP, I am wowed - now that I actually own a QH - not only by his versatility - competitive in trail, horsemanship, pleasure; willing to jump; brave as a lead horse on the trails; about to do his first TREC, completed some pleasure rides - but ultimately relieved that I found a horse with a Good Mind, because that, and that alone, is what makes everything so great. And you can't google horse adverts for that on the internet, or rely on any one breed to provide it!!
