This is your first mistake. You are using your eyes and your fingers to do a job your ears are best suited for.
Don't watch the wallet so tightly. By that I don't mean go over budget, I mean be willing to throw someone $20 extra to get what you really want versus saving every nickel by buying something you've never actually heard from Amazon.
You should be auditioning at least 3, and preferably more, different models, using your music. The less expensive the speaker, the more critical it is to listen to as many different ones as you can, because there is no way to avoid compromise at this price level, and you want the speaker's compromises to match your own preferences.
Make a CD of music you know well; use full resolution 16/44.1 files. If all you have are mp3's or some other compressed lossy format, then go out and buy a full resolution CD of an artist you love.
Disk in hand, get out and listen to some speakers in your price range, getting the sales staff to use the disk you brought, and buy the ones that sound the best to you.
There is no way you can save money buying speakers based on other people's opinions. Use your own.
As to your question, at this price level, there is more "room" for parts quality in bookshelf speakers than floor-standing. You will need stands, but you can buy them later, or build your own for next to nothing.
Brands? You are looking in the right direction, there are of course others. The British live and die in the bookshelf speaker space, so maybe consider some imports (KEF, Tannoy, many others). Also I think you should check out Axiom Audio.
Very good speakers with one foot in Home Stereo and one in Home Theatre make upgrading easy, plus the factory website has some great deals on closeouts and seconds that work well with your budget. Because they sell direct to consumers, they almost always have a few available at a discount, and they have a generous home audition policy. Check out the left sidebar on their website for the menu item: "Special Promotions" or the "Deals" section in the top menu bar.
