Hi,
A couple of us here have started a new render farm dedicated to Blender. It is called Blenderfarm (http://blender.farm) and is now up running for beta testing. Try it out if you like. You get a free hour of render time and 50% discount during beta.
We created Blenderfarm because we felt there is a need for a straightforward, no-nonsense online render service for Blender animators. By building it bottom-up with hardware optimised for Cycles, we are able to offer a price that should make sense even on a budget.
Please try it out and let us know what you think. All feedback is very welcome. We hope that this can become a valuable and useful contribution to the Blender community.
