REI radiant and the North Face Furnace meet your requirements. That and the Kelty are all pretty similar in weight and EN rating. The regular radiant appears to be the narrowest, though the Kelty comes in small, which may fit you better.

I know money is tight for you, and you are already probably stretching your budget, but I thought I would throw this out there. Those three bags weigh 40 - 45 ounces and cost around $200. For $240 you can get an Enlightened Equipment Revelation (or enigma) in short regular that is 18.5 ounces. You might be able to find a used one in your price range.
