i'd check that out. i've had some awesome veggies 'burgs, and i'm an unapologetic carnivore.
benefit that veggie has over meat, in the burger dept., is that the taste of ground meat is too strong. only thing you can do with it is go even stronger: bbq sauce, hot peppers, etc. it can be good, but it's taking a sledgehammer to your palette. a lot more variation (read: subtlety) available when going veggie.
unfortunately, a lot of people's only exposure to veggie burgers are the tasteless frozen pucks of pressed insulation that come in a box and folks throw on the bbq to appease vegetarians. that's like basing your appreciation of pasta on chef boy-ar-dee (sp?).
