I think that may be by design. They are a small, family-owned company and are frequently out of stock on multiple items. The first batch of their new E2XTD heads (which are the equivalent of the Modlite OKW) sold out in 24 hours. I have a feeling they like the size of their business as it is and therefore do not want to (or have to) market any more than their own website, user forum postings and word of mouth.
