I would recommend a physical access device for your new gpg key that you
create. I've heard good things about this USB device:
http://www.crypto-stick.org/
and am trying to have a bunch of them at the Kernel Summit this year to
hand out to people if they want one.

There are also lots of other smart-card form-factor devices that can be
used to store GPG keys. Some places to purchase these can be found at
links from the above site.
