Magnatones are a labor of love. Mine turned out really nice, and that Barth pickup is what makes these basses so cool. My Hurricane, unfortunately, has developed fretboard problems above the 12th fret and the action is really high now. I suspect that the cool outdoor weather from the night I gigged with it did a little damage. I won't be doing that again.
Keep us posted on your progress, and post pics when you've finished it.
