Through the recommendation of another thread here, I ordered this:

Shipping was fantastic, I ordered on Thursday 07/02 and received it on Monday 07/06. Keep in mind that Friday 07/03 was a federal holiday, and I was pretty amazed when I saw it at my door.

Install was a bitch, trying to hold the three pieces (seat, pillion, and backrest) while inserting the bolts, and no easier with my wife helping. Finally got it done through pure determination. Also, the bolts included with the backrest were the wrong diameter, luckily my stock bolts were long enough to reuse.

With that said, this thing is awesome and I'm really looking forward to trying it on my trip to visit family the beginning of next month. Meanwhile, I've been riding with it for a couple days and I like it. Because of the way it mounts (forward of the rear seat), it moves you forward about an inch. This feels odd at first, but it moves me closer to the bars and my highway pegs.
