Neither them or Knoll Crest has any. They've been out for a couple of years. This was one of those cases where being cautious got us burned. We only bought 5 units to see how he worked out. The nxt year when we saw how well he did on our cows we started looking for him again. By then there wasn;t any left.
I put out feelers a couple of times a year in hopes that someone new will have come along that has some just sitting in their tank
