Is there actually a good quality UV CCFL option for PC use? The cheap ones are notoriously unreliable, hence LEDs have jumped in, but they're not proper UV.
I don't think I'd even mind paying a lot for one, as long as it did the job properly! LED's generally aren't much good, although the Darkside ones worked out OK for me... I definitely got a good UV reaction from the Mayhems fluid I used, but it faded by a good 50% or so within a couple of weeks. I think the UV component of the fluid itself does break down though, so you'll never get that same 'wow' factor you get when it first reacts. So regardless if LED UV ages or not, you'll still see some degradation in the effect even with a top quality CCFL.
