I searched ebay when my third long discontinued Logitech VX Revolution started exhibiting intermittent clicking. I discovered that the switches themselves can be purchased, along with the bottom pads that need to be removed to expose the screws holding the mouse together. I was able to successfully repair two. I don't know what happened with the third, but I killed it. Maybe you could try repairing your Trackman or M570.
