Here is the relevant information from the lead designer:

1) $20 gets you a pre-order with beta access.

2) After the release candidate is placed on Steam it will cost $25.

3) It will be available on Steam (with Steam as DRM), Humble Bundle and Desura (both DRM-free).

4)The beta should be available tomorrow on Steam.
