One of the things I admire about Tormek is its fair and balanced approach. I believe there was some bias against the T4 when it was first introduced, a preference toward the tried and true. However, the stout hearted "little brother" has proven itself a worthy competitor. Eventually, Tormek paid for industrial recertification, which eliminated the "thirty minute duty" myth and introduced the three 200 mm diameter diamond wheels, which added to the machine's "oomph". ( I hope this evolution will soon continue with an SB-200 silicon carbide grinding wheel and a T4 flat composite honing wheel.)
Tormek does seem to be innovating into recognizing the need for smaller, specialized machines. Like the English version, this translated German version uses an overview followed by role playing. The two versions are similar. I recommend watching both. Here are links:
