Not certain the trade off between the different UV light sources, but to keep my start into alternative processes within a reasonable budget, I got a NuArc plate burner locally for $100. This included a 20x24 vacuum easel built-in.

It is about 30 years old, but industrial quality and at that vintage does not have any obvious electronics that might be impossible to replace "in-kind". Big and bulky, but cheap...

One of the outcomes of the pre-press business moving to digital.
