Currently sold: the TS4300 (mid-range, modular), the TS4500 (enterprise, frame-scale), and the TS2900 autoloader (entry-level). Withdrawn from sale but still common in the field: the TS3100 and TS3200, officially replaced by the TS4300, and the TS3500, replaced by the TS4500. Withdrawn units can often still run reliably; the open question is parts availability and LTO generation ceiling, not an immediate failure risk.
