I have the grasshopper. It's dirt cheap. It works.
I bought a used Kawi gel seat (it's not any better than stock) and a grasshopper backrest. That's my very cheap solution before I get a Russell. Wife and I are headed on a cruise in June so I'm going to hold off the 5 digit purchases until after that

But probably, when we get back, I'll send the stocker off to have the Russell made. (And in the meantime; the Kawi gel seat will work so I don't have to go without the bike!)
For the price it's not bad. The bracket is decent. The pad is "okay", but the utopia pad definitely looks a lot better. But it works for me. The Russell seat will have it's own backrest. So no sense investing too much now.
For me, once riding a bike with a backrest, I really can't go back. It just makes the bike so much more comfortable.
