Alex, you mention marketing....
Of the three dealers shown on the Ioptron website, one didn't even have Ioptron on its website, and the other was only contactable via online and didn't have any location or prices. That's why I finished up with the Adelaide one, who at least had the info I wanted.
BTW, my obs will be 2.7m x 4.2m used galv iron walls, RO on an old caravan site the previous owner used while building his house. Basically a slightly larger repeat of my ex-Brisbane one. Two piers, the second with AzEq6 for my C8 Hyperstar and CF RC8, as well as a spare slab outside where the wind turbine used to be. Yep, I'm a gadget collector.
I'm completely off-grid both power (48KWh battery bank) because the power company want $27K to connect from the road 200m away, water (47,000 litres), a 2 BR 2B 100sqm house and built it myself with local help where needed. Fled here from the bright lights and noise of Brisbane. (Just sayin' .....).
Turn 75 this year, born in Tenterfield, raised in Drake, know Tabulam well. So go for it Alex.
