I'm about to pull the trigger on a new light, too.

Looking at:

• Cygolite TridenX 1100
• Dinotte 1200L+
• NiteRider Pro 1800

I just can't decide!

I'd love to get the Niterider 3600, not only is it insanely bright, but it comes with software to customize the output. Sadly I don't have $700 for a light.
