In Today's Market, I'd Pass
Just my opinion, but with all the finished show horses (healthy, well-bred, good looking, athletic and WITH points) available out there today at rock-bottom prices, you can do better (maybe for less). Not sure what you're looking to spend, but your dollar will buy more now than ever.
There are so many good horses out there, without signficant 'issues'. Unless you're looking for a project, for the learning experience or just because you like the challenge, I'd pass and keep looking.
