They have been out of stock for some months now, and the primary US importer of them has missed several deadlines now for getting them back in stock. If I were you I would not count on them being here in Late July either? If you need get something going soon The EZM Q-matic might be the way to go? A bit more money but last I heard they did have kits to sell. Check in with a dealer near you.
