I mean, if your definition of "affordable" is free, then sure.
But for the record there are other affordable EU suppliers who do DNSSEC:
- Bunny DNS[0] is "free" – i.e. only subject to their minimum $1/month account spend fee.
- RcodeZero is very affordable[1] plus added bonus it is run by the `.at` registry so the infrastructure is solid – business customers only, no private individuals
- Netnod (only via resellers[2] unless you are a big company or government) – Netnod host the I Root Servers and their public hosting DNSSEC service will soon feature HSM-bound DNSSEC keys
