It depends on your usage.
If it is more of a middle of the night standing naked in your bedroom and trying to see into the window 3 blocks over, I suggest something like
these. To help keep them steady, you could invest in a tripod, since it is actually quite difficult to brace yourself against a wall.
If it is more to get a better look at the sunbather across the alley, you could probably get by with a model, like
these.
