Not sure if many of you guys know already, but Wolffpac Tech has some great LED display kits for 6803's now. They have Red, Green, Orange, Blue and White options available. His kits are very well made and easy to assemble. I recommend a regulated soldering station and a fine tip, as each board has around 420 pads on them. I couldn't be happier with the way they turned out, and I also love being able to assemble them myself like an adult set of legos.
Note, my camera does not show the displays very clearly in low lighting...they are crystal clear in person!
