D5000 repair advice

All,

I have a D5000 that front-focuses.  (I confirmed it using a focus test chart and a tripod.)  I took it to Photo Tech in NYC for repair, and got the following estimate.  It's for $272, which is about what my D5000 is worth.

SERVICE REMARKS

BODY L$89, P$128: REPLACE TO GO PCB                                        LABOR $124.00

REPAIR AND ADJUST SHUTTER RELEASE MECHANISM                   PARTS $148.00

REPAIR AND ADJUST MIRROR OPERATION                                         MISC ($25.00)

REPAIR AND ADJUST AUTO FOCUS OPERATION                                  TAX $0.00

6-MONTH GUARANTEE                                                                 SHIPPING $25.00

LENS L$35, P$20: CLEAN AND REPAIR SAND/GRIT TYPE                  TOTAL $272.00

REPLACE FILTER RING

Does all this need to be done to fix front-focusing?  What does the TOGO PCB do?  Would the shutter release mechanism impact autofocus?

If it really requires $272 to fix, I'll probably just sell it "as is" for $150 and get another camera.

Thanks,

Bryan
