The ST251 works about 95% of the time, and the Miniscribe I have no data on.
It will probably work as well, but I'd need a model number to take a good 
crack at it.  

The big thing is a spec called "Window Margin".  ST251s have this on the 
data sheet.  As long as you have nothing over 60ns you should be ok; I've 
seen a few with slop exceeding this work, but a few that didn't either.

Ps: Your request for a quotation is on the way as well.... :-)
