I don't have any experience with the bikes you mentioned, but you might want to consider something with 650c wheels. You can do a search and find a few good threads about wheel size/rider height, etc.

I'm 5'1" w/ a 27" inseam. My bike has 650c wheels and a 43cm seat tube.

The shop that made my bike has come up with a bike that is just over your price range, but may be worth considering: http://www.rodcycle.com/

For some reason I can't copy/paste a direct link to the bike, but if you click "Randonneur" on the side, the "Navigator" is the first one that pops up. They have a long-distance test ride program, if you are not in the area.

I think Cannondale might also make a small bike, but I'm not that familiar with their product line.
