I'm partial to Ariens, but several friends have had good luck with Toro units (I'm picking up a used Toro from brother in law and a used Ariens from another friend tomorrow). I rebuild what I find or what is given to me and then give them to family members.
My experience with older (1988 and earlier) Ariens is that parts and service are available for just about every model made (I have purchased parts for models from the 60's).
You might consider a used unit from a local dealer, but might be a semi-lame gift, maybe give your husband the option?
In my opinion, your driveway and sidewalk needs aren't that great, you might be able to get by with a smaller unit, but just use patience.
I am just outside of the 495 belt near Route 2 in Mass, so we do get dumped on (but not in the near future :(
Good Luck.
