I am a fan of the "Euro lead." My dad always had them, but he got his from Ray Allen and I'm not going to spend that much on a leash O.O
BUT...I found this, at a much more reasonable price:
Hamilton Nylon European Dog Lead 3/4"
They have them in 2 widths in nylon and 1 in leather - nylon comes in a bunch of colors, leather in black or burgundy.
I have a nylon one, and I love it. It's very good quality (I would have expected it to cost more than $8). It's soft on the hands. You can put it over your shoulder, around your waist, or use it as a regular leash (2 different lengths with one leash), and you can use it to tether your dog to something if you need to for a few moments. You can also hook one dog to each end and hold the middle - I've done this in a pinch, but it's not something I'd do regularly. I've had mine for almost a year and use it all the time, and it's holding up well. I did use a lighter to melt off some frayed pieces from dragging on the ground, but the workmanship is top notch. If you have two dogs, you can put one over each shoulder, and still be able to work them independently, rather than using a coupler.
