If there is a way I can bung you one of those Blackmagics converters without you having to suffer the import tax, such as claiming it as a return or something, happy to do so. I am selling in excellent condition for $120 US, they are $199 new. You'll need to power via 12v, like from a gold or v mount batt, and if so would need a d-tap cable also. Would have to work out shipping but it would be a tiny box. If your local price is notably more than the list price here, might be worth it.
