Greasemonkey[0] is fairly handy for scraping. You can even include remote resources like jQuery if you're targeting specific DOM elements in the page. For storing the data, you can just use LocalStorage (for example if you're paginating)

99% of the time I can easily thow together a simple Python script with the BeautifulSoup and requests libraries to do any kind of basic scraping, form text to images or to API endpoints. And most of the time if I need a to store the data nicely I can either use the built-in csv or json modules or use SQLite database as a single file (which I believe is also part of the standard library)

So many ways to do this. What are you trying to scrape? If its light weight, you could use a Chrome plugin called Data Miner. Right now I am using Beautiful Soup for most of my scrapping and love it. Python is incredibly easy to learn and powerful.

I use PHP http://motyar.info/webscrapemaster/

Try with another. The qkast web clipper http://qkast.com

It has been awhile since I last did this but I used HTMLAgilityPack for .NET.

I've used Phatom.js before. It really depends on the site. Some sites need full browsers running which you could use selenium.

If you like JavaScript you may give Nightmare.js a try. It's so simple yet so powerful. I've used it quite a lot and never had a complaint.

JSoup[0] works fine for me.

Scrapy

This tool felt like it descended from the gods of software. It's a brilliant tool.

Depending on how complicated the site its either

Selenium with Chrome running in a virtual display.
