The cherry parts have been around for a long time. The national parts are
actually easier to get  if you can imagine that. The only glitch is that
you need to typically buy a rail of 40. The cherry parts are very expensive
in any qty less then what GM might buy (if they used them).  They also
can't be used to drive an igniton coil, so a bit less versitile. Did I
mention costly? If you don't need the Peak and Hold injector style drive,
check out the IRF6210 and other drivers, about half the cost, and you can
get them from standard distributers.
