What name does your wife use to post?
Has she tried the HVs to see which one suits her? As I am sure you've noticed, we are fairly unanimous in our conviction that a person has to try a machine before buying - because even the "best" machine may not suit one person's needs. Who can say which is "best" anyway, with so many excellent machines out there now. We're really fortunate with that.
You seem to be very involved. Are you retired? You two might have a great time going around to the different dealers, "test driving" the machines.
