Hi Ed,
A set of Anniversary electronics runs about $1200. If you use your existing filter+Q modules, you can save $500. You may have to slightly route out for the larger jack inside the cavity and reshield that area. If you send me a picture of your electronics cavity I'll probably be able to tell if it will be needed.
You won't be able to do anything with the old SC circuit until you replace the modules (and get some pickups).
Refinishing is a labor intensive process where we sand off the original paint down to the wood and completely repaint. Our price for refinishing also includes refinishing the tailpiece and cleaning all the brass hardware. Usually instruments in here for a refin also need a little fretwork, so we also include a fretmill (or a credit towards refretting if needed). Your instrument will look as close to new as it can with all the existing parts on it.
