I considered one of those also, Evan because it would have been the easy way out. But as I said at the first of this I wanted one with an analog odometer and the GPS units all use liquid crystal screen displays. Not that this isn't a deviation from original...it certainly is, but if I'm right on my calculations it will be almost infinitely adjustable when I finish. And hopefully I'll be able to preserve the re-settable trip odometer. We'll see how it goes.
