I saw just one on ebay for $12 plus $10 shipping (new)

They also have them on
www.amazon.com for $25.00 plus shipping. I've always used the Dex Teddy Bear and sent those home with my new puppies. They have the heartbeat, but not the pocket for placing the microwave gel in. The good thing about these is you can get them on ebay for a lot less. I just had to buy four for my new litter and I paid from $8.00 to $12.00 with shipping included for each one.
