Jet Production in Deep Inelastic Scattering at Next-to-Leading Order
  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.
