For a SE 5.5' he's charging $439; for a 7.5' $509, or a delta of $70 for 2'. Using Nate's pricing, figure 10' of wire to do 4 x 2', so $62.50. Either he's not good at math and using quite different margin calculations in his pricing, or this may give some visibility as to what he is really paying for wire from Jena. And after the R10 recable incident, I can't believe he's doing business with Jena.
Like ALO, etc., he'll find plenty of lemmings perfectly willing to pony up...
