My brother. Repeatedly. Last I bothered paying attention, he had about 3 pre-ban AR variants, a green AUG, a black AUG, two Valmets (one folding-stock), several Benellis, 2 or 3 SPASes, an HK 94, a 91, a 53.... Oh! And he just recently bought a Barrett. That's only the stuff I remember and that doesn't even touch the pistols.
And, to my eternal homicidal rage, he *doesn't shoot the damned things*!!! Safe queens, every one of 'em, all because some jackass convinced him that "they're a great investment". Even he doesn't believe that anymore but it's become "his thing" now. All the local dealers love him - he's put most of their kids through college by now.
Truth be told, I'd probably spring for an AUG if I had a good chunk of disposable cash. *Obviously* haven't gotten to shoot one - I'm not bitter about it - but it shouldered and pointed very naturally.
