Plug In Decoder For Athearn CF7?

[FCIN]

Won an Athearn CF7 on eBay & it had a TCS decoder. In a word SWEET!

Andy;
I'm already looking for a plug-in sound decoder for my CF-7. Couldn't be more pleased with the performance with this Athearn loco. The other CF-7 that I have runs okay but is a lot noisier than the one I added the decoder to yesterday, so will just leave that one as is for now (read - sell cheap).
