DLink Routers support Dynamic DNS now. I have a No-IP account and I run my remote sites with DLink and haven't really had too many problems, except for the odd time where the router hangs and needs to be rebooted but for the savings ($50 for the router) I don't mind having to reboot it once in a while, doesn't result in any lost video so I'm OK there
From what I've seen most consumer routers (DLink, SMC, LinkSys) are moving towards Dynamic DNS support and with Cisco buying LinkSys you are going to start seeing some pretty cool features in their routers shortly, Bandwidth Priority being the one I'm waiting for.
Here's a link to Google on free DNS providers, there are tons of them

Great group, I will be posting often because I have a ton of questions and a lot of answers, especially in networking.
