Request for recommendations

I am hoping/planning to install a "roll bar" in my current TR250 project.

1. Does anyone have experience with the "roll bar" that Moss sells. It seems
rather expensive to me!

2. Does anyone have any experience with an over-the-counter (as opposed to
custom) "roll bar" from any other source?

3. Does anyone have any experience with a maker of custom built "roll bars"?

Thanks in advance,

Jim
