The single biggest complaint about craigslist is the inability to search multiple cities at the same time. It gets very tiring having to click back and forth from city to city to city in order to locate what you’re looking for. Why they have not made this a feature is a mystery to everyone. However, it has allowed dozens of sites dedicated to just this function. Depending on your particular needs one of the many free sites will work for you. Many sites offer a small downloadable plug-in, and charge up to $30 but offer some useful advanced features. I am going to recommend just one site and it’s free, called http://www.crazedlist.org/.
The site only works with the Firefox browser and when you first travel to the page it requires you to change the configuration of the Firefox. It can be intimidating but the instructions are very simple. If you’re familiar with using tabs in Firefox, I suggest you open a new one. That will allow you to keep both the instruction page and the configuration page open for easy viewing. Once you have made the needed change restart your browser and go back to the site. It will now be fully functional for you.
Some of the paid programs allow you to not only search for items but be notified when your particular item gets posted if you were unable to find it initially. This of course can be very helpful when searching for very rare or very popular items. This can give you the upper hand in getting to the buyer first to make your offer.
