To Kim - looking for a cryo machine. Our club, Heart of Ohio Ferret Assoc. & Rescue, raised funds for a Cryo Machine for our vet. Dan Beer, Care Pet Clinic (614-252-4353). I understand the initial cost was around $400. He had to purchase another attachment which was around $200, I believe. Then the liquid nitrogen (I think that is what he said it uses) cost about $75 or so and is only good for about 24 hours. You could have your vet give him a call. Hope that helps some.
