Thanks, all, for the feedback. I am not wedded to any particular design, very much going in to this with an open mind. I do want side-by-side seating to make it more fun to fly with my wife and three kids (one at a time). I am even looking at nosedraggers if they have the performance I need, though real airplanes have always been taildraggers in my mind.
By the way, on the Taylorcraft question, most of the ones I am finding are BC-12D models and other 65hp models, so not enough oomph for 5000' ft field elevation on a hot day, though there is the possibility of an STC upgrade to a bigger engine, especially if the overhaul was due anyway. I loked at ragwing Pipers but the various Cub models seem in such high demand that they cost a lot more than other, comparable designs. Pacers (and converted Tri-Pacers) come up at modest prices fairly frequently but don't seem right for high altitudes. I have seen a couple of C170s under $30k and even a couple of nice old straight-tail C172s that I would consider.
On the financial side, this would be my first aircraft purchase and while I have reached the point in my life when I can manage it, I also don't want to bite off more than I can chew. The budget I set seems reasonable for the initial purchase price of a two-seater or maybe a little more for a modest four-seater, knowing that there will still likely be update and overhaul costs to get the plane where I want it to be.
If I were really going whole hog I'd be shopping for something big enough for the whole family in club seats plus luggage, maybe a Cherokee Six or Cessna 206. But as much as I'd love a flying RV for family vacations, I just can't afford to buy, feed and maintain something like that now, and maybe not ever. And by the time I could, the kids will be grown and I won't need the seats anymore.
What I can do is get something that gets us flying right now, just not all at the same time, suitable for this country and therefore not hard to resell if I decide not to take it with me when we move on to our next assignment in a few years.
Keep those suggestions coming!
Cheers,
Matthew
