I have DSL at my home and settigng up my PC for remote access. I am ready to sign up for a free Dynamic DNS service, but was wondering if one was better than the other. I will probably use DynDNS or No-IP.

There is not much difference (as far as I can tell) between those two. I use No-IP at my home and have set up some customers with DynDNS. These are the only two I have used and I would have trouble recommending either. The updater utilities work about the samefor both.
