Thompson (sp?) has been making a 16MHz 68000 for quite some time now.  That
could substitute until a faster 68010 can be found.  I don't know if any
of the second sources make 68010s, though lots of companies make 68000s.
There may actually be others besides Thompson who are making the fast
68000s, but there is at least this one source.  If you can take much 
advantage of the double clock speed (like, with some 14Mhz memory), you'll
get a big speedup.  The difference between the 68000 vs 68010 won't be all
that great at equivalent speeds.
