amplitudes there are strongly attractive and so when used in a standard optical potential approach may support very strong bindings. One problem that arises at this stage is of a technical character. As these amplitudes are energy dependent, it is hard to account for that in the optical model approach. There exists another, more serious, problem which is common to all approaches. As the energies involved are far away from the physical region tested in KN scattering, the uncertainties in the KN scattering amplitudes are sizable. For instance, if the $\Lambda(1405)$ is a KN bound state, then the amplitude far below the resonance is given not only by the position of the singularity but to a greater extent by the Born term, which indicates a strong dependence on the uncertain interaction range $r_o$. An old multi-channel potential model of Ref. [@KRZ75] indicates that the available scattering data do not allow one to fix the precise value of $r_o$. This unfortunate situation is still actual. The $r_o$ is expected to be close to the inverse vector meson mass. However, even though a change of 20$\%$ in $r_o$ would not affect the scattering region, it results in a 30$\%$ change of $f_{KN}$
