Yeah, things for X10 certainly are looking up and considering the time and money already invested, why not continue down that road.
I'll wait and see if the XTB-IIR solves my current problems. If it does I'll go down the WGL road later after the holidays when I can generate the extra cash. However, if the CM15a becomes the problem, then instead of throwing $80 to $100 at it, I'll spend the extra and get the WGL/CM11a or XTB-232 direction. That gets me back up and running with a solid backbone and future expansion/opportunities. And still for a lot less than converting over to newer technology that still isn't standardized.
