I downloaded the extension and had it up and running in no time. Easy to configure and customize. If you're looking for a free classified extension this is it. What would make it great is if the developer offered a way to charge for ads, even if the extension came with a price. I know PaidSystem exists, but forcing the user to buy credits first before they can pay for ads just doesn't seem very attractive or efficient. Again, this is a great extension as is for free classifieds. A commercial version would be even better.
