I understand the problem you are having. The issue is getting a core. That's going to be a problem.

Like I said...you can call Cam Motion and see what they have, or if they can tell you has that core, or if one is even made.

There is also Barton, and Tim Banning at FHO who may be able to help.

I totally get what you want. The getting part is going to be an issue.
