Two DNS Servers - suits many VPS or two dedicated

What's the nicest setup?

I've now got two DNS servers set up; all works well, I'm happy. They are on separate VPS providers and run nice and fast, so far. Running only BIND.

So; I was adding up the cost of the two dedicated webservers I rent, both in the same DC... and I could get a whole pile of VPS servers for that money.

In fact, adding up the Gb allocations of VPS servers, I'd get MORE bandwidth and disk space from a collection of VPS servers.

So; I am now wondering whether I should drop the two dedicated servers and get a pile of VPS accounts across the web; then set up daily rsync and MySQL multi-master replication across them.

This would give me loads of redundancy and let me play with fancy DNS schemes such as geographical DNS homing...

What think you all?
