I had seen the list of f/w in the MobileRead FAQ - but when I tried to make sense of the offerings at the BeBook & LBook sites I found them to be very confusing.
The Hanlin site was much easier for me - which is funny considering how their language is soooo not english !
I did get the download from there but the single file I wanted took a bunch of tries before it would complete for me.
I am all set now - even have the original one courtesy of the very nice man the latest reader came from - and I suspect that the Hanlin f/w will be very good for me too,
but only time will tell.
If it turns out to be funny I can always zap in the old, familiar OEM one, so it's all good now.
