I've just tested zonesigner from dnssec-tools.org. It was surprisingly easy. If you think that DNSSEC is a complex mess you should try zonesigner. It's pretty much as close to a turn-key solution for DNSSEC as possible. You don't really need to understand what's happening. Just follow the instructions and you'll be fine.

Adding DNSSEC to your domain is still not for everybody, but if you feel confident about administrating BIND, than DNSSEC should be within your reach as well.
