XR table questions

Hello, i have the normal 2x2 crossfire, with all the add ons.

I am at the point that I larger table.

1- Is the XR worth it, or should I consider the STV?

2-Are there any quirks or bugs with the machine? On my crossfire Limit switches cause codes. ThC works, but sometimes causes a code

I haven’t had any issues with my XR, everything has been flawless so far. My opinion worth it. I started with the Pro it has been a great table as well just wanted a bigger cut envelope.
I looked at other brands before purchasing Langmuir tables, talked with people that own other brands of tables they had issues and paid a lot more money for what they went with. I chose Langmuir no regrets…
