In the past I've tried using the free tier of other DynDNS services but with 2 commercial routers I had it always boiled down to the firmware being crap and having some bug that wasn't working with the free DynDNS. Many people recommend OpenWRT but you need to plan in advance which router you are going to buy to be compatibile with OpenWRT and I never planned so much in advance.
