Is the blackToe better than the plans, book, 20" x 40" machine

The blackToe machine is better than the plans machine and this is why: the blackToe machine prevents racking since it has chains on both sides of the gantry; the chain drive provides higher rapid velocity becuase of the mechanical ratio; the chains can be tensioned, so the machine has less backlash overall; the overall structure is much stiffer due to the design of the gantry box form; the structure and mechanics is more compact due to the v-groove bearings having a smaller form than the bearing and bearing truck assembly; the blackToe can receive many more types of routers since the mounts clamp to the outside housing of the router/spindle motor.
