Need advise on rack for turntable

I just purchased a Scountmaster. My current rack is too "flimsey" to support the turntable without the tonearm wobbling in the record groove as i walk across the floor. The room has carpet, and is on the second floor of the house. I'm lookin for something that will keep vibrations away from the turntable, but won't cost me than the price of the turntable I'm trying to support with it.
