Newspaperarchive has recently changed their PDF view window, to make it almost useless. I won't renew.
I REALLY like what I can find on genealogybank.com, but they've recently changed their search page. The results are still good, but it takes a couple of extra clicks to get to the "advanced" search. And, they are having serious server problems - a search times out more often than not, lots of proxy errors and usually have to reload a page to get the old newspaper pages to display.
