I've been thinking about checking out Mechanize, but I've been using BeautifulSoup and a small library of helper functions for a while and haven't found time to familiarize myself with Mechanize. BeautifulSoup is lacking easy form-filling functions, but they're pretty easy to write, assuming that the site doesn't do really funky stuff with their parameters. Basically, just grab all the input and select elements from a given form and put them in a dict, update values, and urlencode.
