  We discuss the scaling behaviour of different fermion actions in dynamical
simulations of the 2-dimensional massive Schwinger model. We have chosen
Wilson, hypercube, twisted mass and overlap fermion actions. As physical
observables, the pion mass and the scalar condensate are computed for the above
mentioned actions at a number of coupling values and fermion masses. We also
discuss possibilities to simulate overlap fermions dynamically avoiding
problems with low-lying eigenvalues of the overlap kernel.
