I haven't seen VoyeurBrazil in a long time but I was always impressed with it. The girls always seemed friendly and there wasn't as much bullshit going on in the chatroom as in other live plugins.
It's not in any South American country, it's on American soil.
LatinaHouse is a piece of shit the last time i looked.
Voyeur Casa is legit.

try hooking up with these guys, direct from Spain - not sure they have any kind of leased feed but you can always ask - if you got the dineros i'm sure they could work with you.
it is weird that there arent' more Spanish language live videochat options considering how many Hispanics in the US
