Popis:	We formulate the graviton propagator on de Sitter background in a 2-parameter family of simple gauges which break de Sitter invariance. Explicit results are derived for the first order perturbations in each parameter. These results should be useful in computations to check for gauge dependence of graviton loop corrections. Comment: 23 pages, 1 table, uses LaTeX2e, version 2 slightly revised for publication
