[s-cars] EM options/comparo

[Scott Munger]

At the risk of opening a topic that may have crossed this board many times
before (which NEVER happens :-) )

What are people's personal experience of the RS2 manifold versus Ned's
extrude honed EM?
Which is subjectively better?  Any test results to show which is empirically
better?

What is the cost of each to acquire (not retail, but really get from someone
at a reasonable discount)?

Thanks!
