Roxy- Consider my beer a little more salty.
I would say you got a great deal on your E-7 heads, and congrats on finding them and selling them at $100 ea. The $2,300 I paid for my E-7 did include crating and shipping from OH to WA, however, which was around $500. Also, since the projector was going to be used as a lobby display, it had to look pristine, not just good. No chips, cracks, blemishes, rust, etc., and it had to have the pearlesque knobs instead of the plain black ones. I finally found this one that with some elbow grease, looks virtually brand new. I may have paid a little more than one would expect, but I'm very happy with being able to find one in such great condition and get it from someone willing to go through the trouble of crating and shipping it.
The Roxy in the old photos in the link above isn't your Roxy by any chance, is it?
