You can get Devon Aire field boots new for around $100, and even cheaper if you can find them used. Those are cheap boots, but they are real leather. They're stiff at first, but break in nicely and last FOREVER. I got a pair as a gift from my mom when I was 15 years old. I'm 25 now and I just sold them last month because my calves outgrew them. They were broken in, but not damaged in any way and were still show-worthy after 10 years of wear. Granted, I did take care of them for the 10 years I had them. They probably would have fallen apart if I had worn them to muck stalls or something (as would any leather boot), but I always made an effort to keep them clean, dry and conditioned, and they aged beautifully. Because they are real leather and held up well, I was able to sell them for $52. So, if you go with that brand, your daughter should be able to get a few good years out of them, and if she outgrows them, you should be able to resell them for a reasonable amount.
