Just got my MXR Carbon Copy yesterday and have been having lots of fun with it so far.  Great sounding delay, but it's the oscillation that's the fun part.  I spent hours just playing with the knobs making wacky spaceship noises, it's an instrument in it's own right!  I' do some clips later, but if anyone's looking for a great sounding delay that doesn't take up much board space, you don't [i]need[/i] tap tempo, and doubles as a noisemaker for experimental projects this is it.  Check out the seller Silverflipz on US eBay, bagged it brand new for $135 shipped which is a bargain as most US stores are selling it for $150.  Escaped customs charges too!  Clips coming soon...
