QCD Lambda parameter from Landau-gauge gluon and ghost correlations

We utilise a recently developed minimal MOM scheme to determine the QCD Lambda parameter from the gluon and ghost propagators in lattice Landau gauge. We discuss uncertainties in the analysis and report our preliminary zero and two flavour results, which are r_0LambdaMS^{(0)}=0.62(1) and r_0LambdaMS^{(2)}=0.60(3)(2), with the second error due to an extrapolation uncertainty.
