best way to sell goods in dr?

I was wondering if there was a site in the dominican similar to what Craigslist is in the states..... In other words, what is the most high traffic site for the dr to post "for sale items." I thought that it might be good to sell my mac computer here being that they are kind of difficult to come by down here. I thought it would be alright if i posted it in the forums but apparently that is a "no-no" and then i went to the classified section in DR1 that was just LOL. Apparenty they are stuck in the 1980's and charge for people to post items for sell-LOLOLOL. It would be one thing if they charged and acted like an intermediary like paypal and ebay but that is not the case. If there is not a site that does this, somebody needs to make one quick.... it will payoff in the long run.
