dolcevita, I was thinking about your husband yesterday. I went to the Midwest Belgian Beer Fest in St. Louis yesterday. There were about 50 US breweries represented, all of which were pouring at least two (and some as many as eight) different Belgian-style beers. It really was a fantastic event -- one I'd happily consider attending again next year. (It was one of the kick-off events for St. Louis Craft Beer Week, which apparently has about 100 scheduled events.)

Anyway...you might want to use the list of attending breweries, cross reference it against Beeradvocate or Ratebeer to see if he can find any others worth trying. I'm sure a lot is stuff that is produced in such small quantities that it's typically only available on tap at the brewery, but some of it must make it into bottles and cans.
