what is the difference between Marshall 1960 cabs and Marshall 1965 cabs...i've been looking at 4x12's for a little bit and i don't understand why the 1960 cabs are easily twice as expensive as the 1965 cabs...

do they even compare to cabs now?
I think it's the model and power rating of the speakers.

And it depends what head you're using, and if you want more of a vintage or "Balls to the wall" kinda sound.
