Cisco,
Most lower end decoders are 2-function decoders and quite adequate. For me, the important thing is to have a decoder that has BEMF or Back EMF for super low-end response.
I have non-silent decoder in my Proto 2000 S1 switcher that also has Back EMF. The non-silent version bothered me at first. But I quickly associated the slight "growl" with the sound of a real diesel locomotive and it hasn't bothered me since. Actually, it's only noticeable at lower speeds and, honestly, hardly audible at all.
If money is an issue, buy some of the NCE D13SRJs. They are 4-function decoders and come with the Back EMF. You can buy them for as little as $13 each at Empire Northern Models.
Hope that helps...

Having said that, some people say that they don't notice any buzz. I don't know if some people can not hear the frequency that they run at or if some engines just don't transmit as much sound, but I would spend a few more dollars to get the silent drive regardless.
Ditto. One day I will pry the shells off and change these out. The buzz is cheap sounding and annoying. Of course I can mu them with some sound locomotives to drown them out.

The few extra dollars for a silent decoder with back EMF is well worth it.

You can buy them for considerably less from Empire Northern Models. Here's the direct link to their NCE decoder page:

Tim's got some of the best prices around. He's also very knowledgeable when it comes to DCC stuff. I can't recommend him highly enough.
