If you can handle the old classics, they're all value-priced except for Guerlains (though L'Instant Pour Homme and PH Extreme are nicely priced). Caron has some great ones cheap (Yatagan, Troisieme Homme). Chanel Antaeus and Egoiste are solid.
Modern classics, dirt cheap, include Dirty English for $20 at Marshall's.
New and distinctive - try Caron Yuzu Man - rich man's Acqua di Gio.
A great deal on some highly overlooked niche - totally unique (especially on a guy) is this Japanese scent, for a mere $54:
L'Eau de Kasaneka - beautiful woody chypre/chypreoid (no listed oakmoss but whatever)http://www.beautyhabit.com/kasaneka.html
No need to spend $140, unless you're buying two frags!
Even Comme des Garçons 2MAN is $95 - amazing scent!
