I shall just mention one option that hasn't cropped up yet, High End Foresight Elements. Once you have settled on a foresight size you may want to consider buying one of these. They are a bit pricey, but they are really good and give a good picture under all light conditions. An added advantage is that they come in a range of ring thicknesses and should you want a very thin ring or a thicker one than that provided by the plastic element the it is available.
