So, an update on this guy. I had a spare digitrax sound decoder sitting around(I know, i know), so I threw it in there. Doesn't sound half bad with a good speaker. Maybe at some point I'll put an ESU in there.
I have to give kudos to BLI. Their electrical pickup sucks, but their support does not. I emailed them about the spare parts for this unit and they were incredibly helpful. I now have grills, windshield, and three non-traction axles to put in there.
As a test I put one of the non-traction wheels in my other unit, and it helped a lot. So I'll replace them all.
