Not all frames listed to be a certain size are the size. Sizes vary by manufacturer and frame type (standard, compact).
Can you go to a local shop and test ride the bike you're thinking about? Once you decide whch size fits you can buy it on-line.
Of course you could support your LBS. If you don't they might not be there when you need them.
