universal adaptor

I have a tripod, monopod, slider and stablizer and they all use different mounting plates. I am looking for a universal adaptor that I can simply stick on top of each device and move my camera between quickly. The only one I can find so far that seems to work is the Giottos MH621. They go for $35 each. Are there better options?

What about arca swiss plates?

Supposedly, so says Joby, "Compatible with virtually any tripod or ballhead! UltraPlate has the universal Arca-Swiss style dovetail, the most common tripod mounting system. You can also attach any tripod quick release plate to one of the extra mounting holes if your favorite QR plate is not Arca-Swiss."
