UPDATE. 2-24-2026. Pre order open. Estimated April shipment. I am working hard to keep up with these. Thank you for being patient. If you have a current open order expect shipment details within the week.
PRICE INCREASE: Due to materials costs I am forced to raise the price on these nearly every batch. Its not what I want but this is what it takes to keep them coming off the shelf and in production.
