Pun intended?! LOL.
As to your real question, about alternatives, I've heard that eHaberdasher's Benjamin line tuxes are pretty slim and are around the same price. Martin Greenfield for Gilt will cost more, about $400 more IIRC, but they make a "slim" version (and the regular already looks plenty slim) and it'll be a very nice suit.
And finally there's J. Crew, where at least you can order separates (though they are probably between SS and MG on price). If you do that, though, you should go with a shawl lapel and the peak has a two-button front.
