Dahon is the good choice
Amigo (a) I'm from Venezuela, and before coming to Canada I was living in Mexico City for 14 months, so I know the city a little bit, the Dahon is very known on folders, very portable also, very easy to carry, and should be lighter than the Benotto model.
When raining is good idea to have fenders!, some times the parks have wet spots, also if you intend to go to parks the Dahon has a rear rack to carry your luch.
So is almost the same price, but Dahon has much more reputation on folders and you get the most for your money.
Remember that you can't lock a folder when you go somewhere, because all the parts can be easily taken apart, you need to carry always your bike, also don't put the bike inside your car in the same place where you are going to park!
