I've been with Newsleecher from the very beginning and this is simply the best binary newsreader for windows there is. I don't know any other program (on any OS) that comes close in speed, ease of use, stability, features and comfort. I absolutely recommend it.
Development may pause from time to time for a month or so but everything new that's added is just well thought out and useful.
And SuperSearch is an amazing feature that saves you tons of time.
