71 dart electronic ignition conversion...

With raising gas price, i figure its time to toss out the points for better performance. I am curious to what the best kit would be for it? I know theres a few kits on ebay and just trying to figure out what would be the best choice. I am not sure if theres one out there that doesn't require a huge orange box on the firewall, want the performance but not the whats that question.
