Smart/Android TV or Android Box with Monitor

[TheSeeker]

hello,

someone has asked me to suggest options in smart/android tv, within a very limited budget of 10-12k. i advised an android box + a monitor as an alternative setup (both, used). could anyone pls suggest which of the two would be better in terms of cost, useability, life etc.?

and any suggestions on the models themselves pls, for android tv & boxes for that budget? mi tv, acer, toshiba etc. come to mind.

thanks.
