Replacement Altimeter brand names?

In the continuing saga of my altimeter woes, I've discovered that
my current unit has been forced into obsolecense. It's a Macleod unit,
and most overhaul places say they won't touch them. The guy who did the
IFR cert says, "Buy a brand name like United or Kollsman."

Any thoughts on one vs. the other?
