I've been charging $75 including return shipping to do a Sega PAC... probably on the low side since its such a pain in the butt. Though my theory is you have to compete a repair price with a replacement price. When you can find them, loose Sega PACs seem to sell for $75 to $100 or so. Though that reasoning is losing value every day since any non-refurbed PAC is bound to fail and fail soon!
