Amon - self-hosted server and web app monitoring toolkit

The pricing scheme drastically needs a change. The free level is fine, but there needs to be at least onepaid intermediate levels: 2 apps, with features between free and plus. Why? If a developer is doing 1 hobby web app and wants to take it to the next level, a 2-app plan will both provide support for their current app and allow breathing room in case they want to go for a second.
As a web app developer myself, I would not pay for the Amon Plus plan. I have 1 web app running on AppFog. I don't need to pay for unlimited servers and unlimited apps. I would pay for basic support, but paid basic support is not available in the two tiers offered.
Are they crazy? What if they loose this domain for some reason, and somebody puts different code there.

[edit] Update: Manual installation was successful, but nothing runs on localhost:2464
Is that the Ruby client Ramon or Amon itself?
With that said, if you're looking for deep insight for performance, metrics, etc - then I'd still have to say that New Relic would be your best bet.
