Are you talking about halfpads, or the other pads skito makes?
I bought a skito halfpad and really loved it... at first.
I think the one the saddlery sold me was slightly too small to begin with and now the foam seems to have shrunk, and doesn't fit properly under my saddles anymore, and I had to duct tape it a bit at the front and back because the foam was tearing. Good how interchangable the inserts and stuff are, but for $120 I would like them get a bit less wear and tear.
Price does seem to be fairly standard for halfpads with removeable inserts though, Zilco makes a foam halfpad with removeable front or back inserts for about the same and I think Grainge has just made a sheepskin one you can put foam inserts in, both are around the $120.
(This is talking about in Australia, it might be completely different where you live!)
