Any trail runner that feels good in the store for a few minutes should be "good enough" to start with. I would focus on comfort first, price second, all other considerations don't really matter until you have an idea of what you like/dislike and what works best in your terrain.
Some points to keep in mind though:
No waterproof shoes. Don't let the salerep talk you into them. Sneakers are low topped and water will flood in from above anyway (I have a waterproof pair and NEVER wear them because they take way too long to dry out).
Your feet swell on the trail. If a shoe feels comfortably snug in a store, it'll probably be too tight out of the city. Despite the common wisdom, I've never really had a trail runner "break in" and feel much more comfortable after wearing a while. Find something snug, then size up a 1/2 size or more (some folks go up even more than that. Depends on your tolerance for floppy toes, how much your feet change, and probably width of foot). So take that into account.
Buy from REI or some other store that has a great return policy. Especially if they fit you…that way if you get some "expert" sales person that sells you a bum shoe, you'll be able to exchange for a better size or brand.
The lighter the shoe, usually the less durable. I prefer really light and flimsy shoes but also am fairly nimble footed so rarely tear up the tops. If you're new to hiking and your region has lots of rocks or plants to snag your feet, getting something a bit heavier but durable will make you more happy as you learn and grow in experience.
Minimalists shoes are amazing, but they aren't for beginners. Get something with a rock plate and decent padding under foot (still avoid any pronation control shoes though) so that your feet aren't totally beat up at the end of a day. I started with some light but decently padded Inov-8s and love them. Only now that I've been walking in vibrams five fingers in the city consistently am I really feeling padded shoes "limitations" on the trail. So don't get too overzealous on that front (if you're even interested in it).
