Which Android TV should I buy?

[mariano_quilmes]

Hello, I would like to know which of this three devices has the possibility for future firmware updates with Openelec or to know which ones have the best support from the community. I have read a lot from Tronsmart, but the other two I do not know very much.

The links are:

I really don´t know who manufactures the second box, I am quite lost with all the alternatives around.

I would like to know which one is the best bang for the buck, but without risking no future support.

Thanks in advance.

Mariano.
