Most I have ever spent on a collar was the $60 on Lily's "For Ella". I like Scout's customized "Gertrude's Son" a LOT better, just because of d-ring placment and the different buckle that I got and the fact that there is no suede to get icky. Scout's was like $53 after shipping because I took advantage of a sale.
That said, they wear their Stillwater nylon collars a LOT. They worked out to about $6 each because I ordered a bunch at one time.
I find it kind of ironic that Lily is wearing a $6 collar today with a thirty something Fetching Tag clipped to it by a $7 Rubit tag clip. She hasn't lost or trashed her tags since I got them though, so I feel like it was worth the large price.
I think after the nylon collars die, I will probably get a tufflex collar from gundogsupply... for like $10. Its just easier to clean. However these nylon ones are going to last a really long time... they may be around for the dogs whole lives. I like having some fancy doggie bling, but yeah majority of our lives take place in mud, water, and cow poo so it'd be stupid to pay Paco's ridiculous prices. I'm sorry I do think their pricing is ludacris. Its grand if you've got the cash, but I don't and likely never will.
