Won't start by itself Part III

[gregsj@mail.imm.com]

Fellow Audians - the starting problem with my '91 200 TQW is definitely
the ignition switch. The good news is the switch can be rebuilt for
$50. The bad news is my new mechanic claims it will take about $300
in labor (@$50 p/h) to remove the switch, fix it and reinstall it.
He claims he's never seen this problem before which means they are 
doing this repair for the first time. Six hours sounds a bit excessive
to me. Is there a rate book that sets how long this repair should
take? Have any of you had this done or done it? If so, what did it
take? TIA for your advice and counsel. Greg
