I just went to the tack store recently and told her (the girl that helped me) I couldn't afford too much. She brought out their lowest priced pair and I tried them on. They were Ovations and were REALLY nice! They are a very good brand for the price, I thought they were almost as good as my Ariats actually. Devon-Aire is good, too. Their clothes are awesome as well. As for Dublin, I don't like them. They are pretty cheap and my friend who got them said they were pretty uncomfortable as well.
I wouldn't buy tall boots first time from ebay
, though. If you get sized for them maybe, but they are really confusing at first.
(I went with Ariat Challenge 2 zips though: they were shiny + I'm a girl = mine :) )
