Lowe Alpine, Marmot, North Face, Kelty, etc. They all make pretty quality gear. Just make sure you get the right size for your body, and the features you want. Also, if you're carrying it for long periods of time, you might want the lightest one you can find.
BackCountry.com is a great site for gear with reviews and good customer service.
I prefer Osprey myself, but a bag is personal.
Whatever pack you get, make sure you get it fitted for you in a store like REI, EMS, etc. They'll fill it with weight and help you adjust all the load straps to get the best fit and center of gravity. It should be free.
Go to an REI that is near you. Almost everyone who works there is an expert in the department they work in. You need to make sure you get the right kind of backpack for what kind of hiking and traveling you are doing as well as what kind of fit and load you like. Their selection is large, knowledge is top notch, and prices are pretty fair. Plus you will be able to get a pack and try it for awhile. Don't like it exchange it to find the perfect one. Learning you got the wrong pack while in the middle of your trip will not be a good experience.
Especially if your gearing up for a major trip, you do not want to buy a backpack sight unseen. Think about your hiking boots, would you buy them mail order? What if they don't fit? or what if all the 'features' described on the website just make them heavy and stiff? A backpack is just a essential a piece of equipment as your boots, and needs to work with you in a way that can't be evaluated over the internet.
Everyone's right that fit is most important. Try the pack on with some weight in it and walk around. I use an Osprey pack, which I've used all over India and South America, and love it. It's like a less expensive Arcteryx (which are great, but pricey). The Ospreys also have hip belts that are molded to your body, making them extra comfortable.
I'm not sure this is exactly what your looking for but check out Duluth Pack. The make great canvas packs that last a life time so pick your color wisely.

Best packs out there bar none. I took my Dana Design pack for an 11 day trek up the Pacific Coast of Costa Rica. These packs expand to hold a ton of gear and are super comfortable and light.

Cruz is headed in the right direction. You can get packs with the Mystery Ranch design influence and features from CamelBak. They were made as part of their collaboration with Mystery Ranch.
However, I would recommend Kifaru as an even better, even stronger alternative. Their construction is the nutz. Their user base consists of individuals that depend upon them not only for sustainment, but to carry a combat loadout in some of the toughest terrain on earth. If you can't trust this pack, you're pretty well screwed.
While in Costa Rica, make sure to hit Witches Rock for killer sets, and, Tabacon Resort for hot springs and pools fueled by the local active volcano, Mt. Arenal.

i'd say Maxpedition or Kifaru - both lean toward the military side of the market as opposed to Jansport which is great for a 4th grader walking 2 blocks to school
