I think he is talking about me !
I paid $950 for my 416 and that was a good deal for its restored condition .
My 101 a2 trailors were all around $300 and my 105a2 trailors were around $170 .
are you sure it is the ctis valve and not the air drier .
a bad drier will make the compressor shut down and not produce air .
It happened to me at a air show this weekend .
a new drier fixed the problem
