I have been in contact with T-Tech and in late July early August they will be coming out with a new tip design and disposable tubes to use with the tips. That is the reason for them not having a lot in stock. Also the HM La Nina I just got, works great as an all around machine. Lined and shaded this today with a T-Tech tube and needles.
