Yeah, I think you're right.. Many people neglect this aspect, which is a big mistake in my opinion. A good rack/support makes a BIG difference.
On a budget, I would strongly recommend trying to find a heavy and well-balanced platform of some sort to put at least your CD player on (I've found the CD to be most sensitive to vibrations, but that may differ between brands obviously). You may want to experiment with a self-made wooden block, a granite block or something similar. All materials will make a difference, it's up to your ears if it's for the better or not though.
After that, you could play around with some of the various equipment feet and support tweaks that are around. You can go a long way with a careful setup and not too much money. :)
