We have a Cane Creek Thudbuster on our Tandem and it is great. A word of caution though. The mechanism is ~4" or so tall, and we got quite a surprise when adjusting the seat height. I had to turn the seat mounting fixture upside down to lower the seat height enough for my stoker and she is 5'8" tall.
I have Cane Creek's eeSilk seatpost on my single, and it fits well and is very nice.
