These waves are extremely small, and we've just managed to build instruments sensitive enough to detect the very biggest ones.

Earth bound instruments will no doubt get better, but to get a real jump in quality, you need instruments in the stillness of space: http://www.einstein-online.info/spotlights/eLISA

It's important to know that LISA and LIGO aren't really competing for sensitivity. Rather they complement each other by looking in different frequency ranges. The relationship between LISA and LIGO is analogous to a radio telescope and a gamma ray one. They observe different parts of the spectrum. At the frequencies that black holes merge for example, ground motion is not much of an issue, and other noise source dominate.

The info on eLISA is great.

I am just waiting for the $10,000 shielding for high end speakers to keep gravity waves from interfering with the acoustic purity of the sound they produce. :-)

You absolutely must keep your record player suspended from glass fiber in a vacuum chamber to avoid any unwanted coloration. Just takes 30 minutes to pump down when you want to flip sides.

I will happily sell you such shielding for $10,000...
