Unfortunately unless you find people local to you willing to share their equipment you have no options. You can hold a razor in your hand, in a store that sells them (as Harold suggested) but that goes only so far. The reality is that holding a razor is awkward until you build the muscle memory.

There should be a cost to trying out something as personal as a razor. I mean would you want to pay full price for a razor that somebody else has returned? There is always the secondary market so you can recover part of your cost, but there is no way to know what your preferences are until you go through the process of trying out different things.

The best option is always going to be to find somebody local to you and Atlanta sounds like a pretty big area, so chances are there are more people than elsewhere. Look around the forum, make some friends - you already got an offer to meet somebody an hour away.
