NLO corrections to jet cross sections in DIS at HERA are studied, with
particular emphasis on the two jet final state.
High jet transverse momenta are a good criterion for the
applicability of fixed order perturbation theory.
A ``natural'' scale choice is the average $k_T^B$
of the jets in the Breit frame, which suggest analyzing the data
in different $<k_T^B>$ intervalls.
