Found it too late when the Bosch HEC718 cacked out.

Does anyone know of a good instrument repair place that I can post to?
Was talking to a company in Adelaide some time ago called Gauge Works on Port Rd, Albert Park. (08) 8445 6644. Was discussing repairs and some of the quoted costs sounded very reasonable to me. may be worth a call.
