Thanks for your interest! Please take a look at the forum threads as the first post discusses expected pricing – also sign up on the interest form linked over there if you have not done so already.
I would recommend the Model F over the beam spring if you are new to both options; plus the Model F’s will ship a lot sooner than the beam springs.
* Cost: Approximately $500 to $600 each for the early birds – about $4 or so per module if you think about it (plus the cost of every other part of the keyboard)! Rather than the made to order model of the Brand New Model F Project, for this one I have already purchased two batches of 150 keyboards each at a higher expense than expected due to project cost overruns. Instead of increasing the price for everyone I expect to offer the first 100 keyboards at one price as a reward to the early birds. Then the next group will be offered at $100 or so higher in pricing, and the final remaining units will be offered $100 more than the last group.
The sales will be in rounds – not sure on any further details though. But yes the later rounds will be increasingly more costly compared to getting in on the earlier rounds. I expect closer to $600 for the first group.

Will there be normal sales after the early bird. If so will it be around 500 like the first round or 900 like the last round
