Crappy Tire has a gel seat cushion on sale for only $9.95. Bought one yesterday and went for a 3 hour ride. Just put it in top of my FJR seat and sat on it, it's rubberized on one side so it stays put. Felt a bit weird to begin with...a bit higher, wider and sorta mushy. Then as I got used to it, I realized it killed vibration and was very cushy...my butt thanked me. Low tech and not glamourous but effective for long rides. Great for grinding down the I5 but you will probably want to leave it at home when you're going out to drag a knee.
