There have been some serious enhancements over recent months, such as the ability to 'whitelist' (only crawl) pages containing a search term, the ability to extract multiple classes / id's (as separate fields in the output file) and a class/id helper which allows you to visually choose the divs or spans for extraction.
Now that the earlier beSta is about to expire, it's time to make all of this a full release. The price is a mere 5 US Dollars, for a licence which doesn't expire. The trial period is 30 days and the only limitation is that the output file has a limited number of rows so that you can still evaluate its output.
