Adapting CO2 regulator to 70:30 Beer Gas bottle

[muppix]

I've been using CO2 to carbonate and serve beer for just over a year and would like to try a 70:30 Nitrogen / CO2 mix, mainly because we can't get any CO2 right now where I live. I have however sourced a great big bottle of this Beer Gas, but it uses a different regulator connection. A quick search reveals a multitude of adapters such as this one which look as though they might fit - at least from looking at a dedicated Nitrogen regulator - but I'd appreciate a heads-up from somebody who's been here and still wears that T-shirt.

Not to worry - found it. Wonder why it's more expensive than the Argon adapters ... ?
