Is it just me or do the buttons on the T2-C feel stiff or heavy? - to a point where my fingers almost get fatigued when changing channels. I've had to return a unit for a sticky scroll button and the new one has a creeky cursor button. After some use it really starts to annow me. I much prefer the more positive feel of the T2+ and T3 buttons. It looks like the new models are going the same way as the T2C.
