I bought a couple of nos (new,old stock) locos from some guy.  One of them is s Bachmann Spectrum EMD SD-45 diesel, product #82709.  A gorgeous loco that I want to get online.  I don't know if it has a decoder or not: I haven't put it on my test track to check and I haven't taken the loco apart, yet.  Going by the box information and sheet inside, it does not have a decoder.
Does anyone know if this would be DCC ready?  (I could find out if I took the cover off).
What decoder should I use?  I have Digitrax DCC (5 of my 6 locos are Bachmann), including their decoder programmer so I'd like to stay with Digitrax.  However I know how good Soundtraxx decoders can be and am considering that brand.  What do you guys think?
If it's not DCC ready, is it worthwhile to make it so?  (I know it's a lot of work)
I'm a newbie, just started with trains and DCC
