Likewise, we only have ~300K entries, and we have been running the 2.0.x
series since August.

We're doing similarly, we have 3 Dell 2550's running FreeBSD (4-STABLE),
with a single master with multiple slaves. Things have just been working
great so far! For now, we are spreading load with a simple round-robin in
DNS, but we'll be trying to put the servers behind a layer-4 switch as soon
as we can (finally) get the L4-switch hardware in-house and tested.
