Punching bag

it's expensive, but try a cornerman stand. It will allow you to hang a bag in the corner of your room. However, noise will still be a problem.

Wavemater sucks.

Lordtariel, did you ever put sand in a stand up heavy bag? Seems to work a little better than water. Unfortunatley, training bags are necessary to have in a dojo. Most students who are trying to learn how to perform proper strikes cannot make the wavemaster filled with sand move across the floor. But it is a good goal for them.
