if you have free electricity s9 is a very good choice
you are looking at the ROI of 7-8 month with the current difficulty level
from what I know,Venezuela is very poor on a brink of financial collapse due to the oil price hitting the new low every month
and OPEC unable to make up their mind as to cut the oil production or not
not sure if buying mining equipment is a good idea in your situation
especially if you spend all of your savings on it,risks are huge
The potential profit is also huge; it's a coinflip in this occasion, but the S7-LN could also work just fine, as well as the regular S7. you are looking at the ROI of 7-8 month with the current difficulty level

Anyways, i'll go ahead and say that this thread is probably dead already due to the OP not responding in a very long time. With nearly free electricity, which I expect will probably happen due to OP living in Venezuela, it's possible to get very quick ROI on pretty much any miner not any older than the A6 or S7. That said, as of now, mining with bitcoin really isn't the best option for many people even with good electricity.
