I have something similar to this (I didn't pay anything near that amount though..got it on sale somewhere years ago) and my dogs do choose to drink from it before the 'normal' water bowls, so don't know if that would be any good for you?? The water doesn't gush out it just refills itself slowly as they drink. Just trying to find a link of something similar.

Okay sort of like this one but it's more of just a bottle upsidedown??? (I'm no help really!!)
