I think that's actually a good deal on leather tall boots, but maybe that's just me. Depending on what you're doing, you may want dress boots rather than the field boots.
But I show in field boots all the time xD.
Ariats hurt my feet (I have wide feet). I bought some Devonaires at the last horse show when my zipper broke, one of the boots fits awesome, the other wouldn't zip. I had to stretch the other but they are comfy.
Personally, I would invest in a pair of field boots. I bought a pair of Devon Aire's when I first started riding english. They lasted barely through the summer, weren't tall enough, and looked cheap. I've owned a pair of the Ariat Heritage boots (pull on) for five years now and they still look near brand new. They also broke in super fast- I think after two rides? :)
