I've been on a TCS kick for 4+ years while converting my locomotives. I still love the warranty but for new decoders, I'm thinking of going with Zimo because of the performance. I have ~10 of the Zimo MX 6-pin decoders installed in Fox Valley GP60M/B and GEVOs and they are super smooth and slow. I haven't tried their hard wire decoders but with the price increase on TCS, I'll give it a try.
