Marketplace can search all Craig's List regions, categories, and subcategories. It supports all the filters the website has: title-only searches, image-only results, price minimum/maximum, etc. On top of what Craig's List provides, Marketplace allows users to filter their initial results down even more. Users can save their favorite entries to return to later or leave Marketplace running and it will refresh searches automatically and notify users when new results are found.
The 1.0 release brings many new features, including the ability to search specific subcategories, more search options like price min/max, and Growl integration. Marketplace makes Craig's List searching faster, easier, and more painless. Marketplace can be downloaded from their website. It features a 25-day trial before users must buy a license. Marketplace requires Mac OS X 10.5 or higher.
Marketplace has been in public beta since September 2008. Touted as "Craig's List, without the ugly," Marketplace functions as a Craig's List search aggregator. It allows users to search many regions quickly, filter the results by the relevant criteria, and then save the interesting finds.
