How are they going to get the parts for just one octo.? Also, if they aren't certified by the mfg., technically they shouldn't touch it even if they are capable of servicing it. Australia isn't exactly a country next door. I don't see the point of getting a HOG octo if HOG has no support or presence there. It would make more sense to buy a brand that is supported in the OP's area even if it isn't a SP brand. I would go with a SP Octo. just to keep things easier to service and source parts for them. I have had different brands for octos and main regulators and it was a nightmare trying to synchronize the service and tuning the second stages when I had to send them to different service centers. It is much simpler and a lot less headache and much less expensive to keep it all in one family (adding a part that isn't even supported in the country is another headache and major pain to say the least). The HOG octo maybe cheaper to buy but it will cost money to ship to Australia, pay duty and then worry about how to service, WHY go through all of this for a HOG brand???
