We are going to start a pre-order process, but we've been waiting until we know the estimated shipping date and also the final UK price. In other countries, our distributors may also start a pre-order process. Our pre-order price will be a discounted price from the initial selling price.
We expect to know within a month what the delivery schedule will be.
Meanwhile, if you PM me with your email address, I'll add it to the list of enquiries about pre-orders.
