I am looking at Ledger as a possible replacement for QuickBooks and wrote a Ruby script to convert my full QuickBooks transaction history to a Ledger-compatible data file. In case anyone else finds it useful, I've put it up as a GitHub gist <https://gist.github.com/3765100>. I also wrote a blog post explaining basic usage<http://www.timetiger.com/gene/blog/2012/2012-09-23-an-alternative-to-quickbooks.html> .
