There is ledger-mode and beancount-mode which are both nice (depending on which program you use). I would say the majority of what I do in practice Python scripts to convert statements to ledger; the amount of stuff I do by hand is minimal enough that it would be easy to live without the emacs mode.
I use emacs + beancount-mode + some helper elisp scripts.
On average, it takes about 30-40 minutes per sitting to do a weekly review, and that's mostly checking g what hides behind amazon/ebay/Google payments.
