Hi abe,
The answer depends on your budget and needs: do plan on buying electronic drums just to keep it quiet, or you are more into recording? If you are more into making music then you might want to consider buying a midi controller, for example, which would give you a vary of options and extensions.
The First advice I can give you right now is that Buying an electronic drum set requires also a good sound system and a monitor so you can hear yourself. You can use headphones, but it doesn't have the same "feel".
So narrow it down and I would be glad to help you
