Praise then darkness, and creation unfinished

I have been using Stanza to read ebooks, and carelessly said "yes" when iTunes suggested an upgrade to iOS 5. It turns out that kills Stanza; any thoughts on other good iPod ereaders?

I googled a little yesterday, and since it seems as though they all cost at least a few dollars, I'd rather not just download randomly, and advice from people I know seems somehow more useful than from random strangers on a comment thread somewhere.
