4Mb of 60ns DRAM is abundantly available for about $150 in small quantities.
That's less than 10% more than 70ns parts.  My supplier tells me that
he often gets 60ns parts when he orders 70 because his supplier is out
of 70's.  Keep in mind that both parts are manufactured exactly the same.
The only difference is that the ones that don't test out at ~50ns get the
70ns label.

I have run 70ns parts in a 486/33 with 0 wait states.  They work just
fine, but for the tiny price differential, I'd specify 60s.

Were these more than just my opinions, they would have cost a bit more.
