I have one very similar. It isn't worth selling, because I can't get out of it what it is honestly worth. Upgrading it is silly, because they charge almost what you can get a used one for to upgrade the old one.....see what I mean?
I just keep mine and use it. I have never needed eyes, and the bolt will bounce off the cheapest brittle paint without breaking. It is sort of like a Mag with lvl 10. (Not quite as gentle, but you get the drift) The eyes are a little silly on an Excal, IMHO. If they are there, then fine, but putting them on an older Excal just isn't worth the cost.
Looks like a nice shooter.
