I have several Pacos and love them. They have been through the ringer and still look good. Studs have fallen off of every collar though, but they are more than willing to send you more studs/rhinestones or you can send the collar in to be repaired. Ana has come a couple times to Atlanta to teach collar/leash making classes and is awesome.
If you want a cheaper Paco, you can call during a Sample Sale. The collars they list on Facebook are at a discount but also, if you call during the SS, any of their sample collars are up for grabs at a discounted price - you just have to ask what they have in their store.
