I've had my computers repaired, sought advice and bought hardware at Bitronics Upper Ferntree Gully. Wes, the owner is very knowledgeable and helpful. There is a reasonably fixed price guarantee for servicing computer which is thorough and comprehensive. A fairly good range of hardware and software is available for purchase in the store which is conveniently located and less stressful than going to the large shopping centres. Sadly the owner has passed away and the business is closed
