NY's system is pretty good. Something you don't mention but is another nice bit is they have poll observers from each major party watching at each elction site. One thing they don't have but I wish for is that, after the machine-count totals are in, each party represented should be able to name a small number of precincts for an audit/hand recount. Parties at this point have pretty good modelling of expected results at a precinct level. That would give a cheap way to get lots of certainty against tampering of the machine vote counting.
