HTML Scraping methods?

I'm sick of manually browsing the 5+ local craigslists, and all the aggregator sites are shit, I want to write my own personal craigslist crawler.

What method would you use for this?

I don't know much PHP, but I'm pretty good with Javascript.

I would write this in a real language like C#.

Something like:
1. Fold through each craigslist city and apply search term.
2. Return links.

use perl

I've done a lot of scraping with Python + the requests library + beautiful soup.  Alternately there's Ruby + Nokogiri.
And if it turns out that craigslist is a bitch to scrap, there's Python or Ruby + Selenium (headless browser)
