First

Might say Hi in the new members section.
Surprised no one jumped in. I would start being patient and look for the breakers and keep checking eBay. Every day, twice a day and just wait.
I've seen them from $150 to $800. While other clusters like the Speed Triple will plug in directly. At some point the ECU won't have it. Will not allow you to load a tune, not sure how the bike would behave.
IF you can get a new one, you will pay dearly for it. Will suggest a water type bag and not allow water to sit on your cluster. Many have had switch damage of the three button clusters. Still have about 50 switch's around here.
Good luck with the hunt.
Also try the other Triumph forum. Forgot, they are a tad banish happy and tip toe around to not be banished. Not worth the effort IMO.
I will say in very bright light, I would move my head around to get a better view. The Fuel and temp the hardest if memory serves.
