Lenie,
You won't regret it. This gauge set is amazing. I have to power it up for everybody that comes to see the car. My favorite view is with the shop doors closed and lights out - it just pops in the dark. It also has a dimmer system built in so you can adjust the LED brightness with lights on or off.
I can't comment on one distributor better than another.
Dakota does sells direct - they also have a dealer locator on their site:
