Anyone use a DF-17 adjustable PCV?

In my never-ending quest for improved idle and just-off-idle manners (big cam 451, 8" vacuum), I'm considering investing in an M/E Wagner DF-17 tunable PCV valve.

But that little billet piece is $129.99... before I spend that much, I'd like to hear from anyone who's actually used one, and did it help?
thanks.

I have one and I don't think much of it. It should work but I think they made it too complicated so it is actually kind of hard to figure out. I ended up making a fixed orifice PCV which works just fine. A fixed orifice setup actually works really well with a big cam and it shouldn't require too much work to make one.
