Definitely go with Justin's. I wear my ostrich Justin's everywhere (probably shouldn't be so hard on them) but they have lasted me five years and are still going strong. After a good shinning in the Denver airport before NWSS each year they look as good as new.
The comment about Ferrini Boots is right. They look pretty, are cheaper, but don't hold up.
One think is to keep in mind is to find a good cobbler. I always where my heels down on my boots and for about $20 bucks I can get new heels caps and they are as good as new again.
