Isolation Devices: Any Good Ones?

I suggest you make your own isolation devices. All you need are some MDF boards (from Home Depot) and rubber equipment feet or casters (from ebay or amazon). You just need to sand and spray-paint them. Pretty efficient and cheap.

I have a bunch of these under my stuff and haven't looked for anything else since I got these.  They are slightly sticky which is particularly good for the blu-ray player which gets bumped a lot inserting discs.  The company also makes bigger, smaller, square, circle, dome-shape.  Tons of options.  

Dont spend a lot.  Unless you have money to burn.  In that case, buy these still and send the rest of the cash to me.  

For cheapskate DIYers there's really no substitute for bungee cords. Mass on spring isolation. Real isolation. 

Look at Loyd 1 I'm now using them on all front end stuff they look great and sound even better.

What's "Loyd 1"?
