This post is old so I am sure(i hope) that a compatible pen was found. I just purchased this one from Petsmart online.Its pricey but I feel it will work for my home and needs. I looked at plastic,metal ect ect.
here is a picture of the pen..perhaps a new or old user will like it as well.http://www.petsmart.com/media/ps/ima...1431_4f415.jpg
