Lemme know what you guys are looking at. Specifically look at what components it has on it. Giant, and many others, have a nasty habit of putting good rear derailleurs on the bike but crap everywhere else. Fit issues are different from type to type. What you would be looking for regarding standover on a road bike is not the same as it would be for a mountainbike.

I worked in a bicycle shop for four years through highschool and college. Giant makes good stuff. They account for nearly 70% of the frames sold in the US. Giant is the world's largest frame supplier and make frames for Schwinn among other labels.
