NCE, DIgitrax and TCI all have drop in non-sound decoders available. They don't fit all locos so you'l have to do some comparison shopping. Hard wiring decoders is pretty straight forward and saves on the cost of the decoders (NCE has one for $15 - I have over 25 of these), the wires are all color coded which makes it pretty easy to wire them up.
