For cheapies, try Brut Classic, Dana Canoe, and Pinaud Clubman. These are all pretty good and representative of the fougere category.
I would also recommend Paco pour Homme and XS, YSL Jazz, Aramis Tuscany, Ralph Lauren Safari, Lauder for Men, Givenchy Xeryus, Cartier Pasha, Van Cleef and Arpels Tsar, Lagerfeld Photo, and Cacharel pour L'homme. There are many fougeres out there, and these are only a few of them. These are well known and most aren't too expensive.
Also try to at least smell Penhaligon's English Fern or Trumper's Wild Fern to get a better idea of what the original fougere conception may have smelled like.
