Thanks to this board, I just saved a lot of cash. :D
It turns out that I already have the PVL, German made, coils. From a post I read the other day I learned that these are the same as the Nology coils. So, I just saved $200+! I'll put that towards my valve adjustment.
Thanks again for such a great source of Steamer info. :D
On a side note, I found a dealer on eBay selling Nology coils for $64.99/ea. They're listed as $69.99 on the Nology site.
