Rena Heating Cables

Let me apologize up front for this repost.  Just before Christmas, I 
made a post to the list asking if anyone was using Rena Heating 
Cables.  When I returned to school in January, the university 
made some unannounced changes to the electronic mail system and 
deleted huge files of inbound e-mail.  So if anyone responded to the 
post, I didn't get to see your response.  Are any subscribers to the 
list using this substrate heating cables?  Does anyone know of a 
source for them?  Costs?  I've contacted the company and requested 
some literature on that and other products.
