HiVi 3.1a Kit Availability

OK, I'm getting lazy in my old age, so I'm looking for a kit where all the hard work has been done for me.
Hence I'm looking at the Swan HiVi 3.1a Kit, which even includes flat-pack cabinets.

However I'm having problems finding outlets.
I live in Australia, but have always used Shipitto in the past, so buying from a US outlet shouldn't be a problem.

Ideally I'm looking for a kit with the Sehlin mode to the crossovers.

Anyone know of any current outlets?
Maybe the actual manufacturer?
 
I reached out to Swan and this was their reply:

Yeah, I was definitely going to use Scott's mod in the crossover.
Actually I'm having so much trouble trying to get a kit, that I might build my own.
The measuring and crossover design doesn't scare me (although I haven't done a design in over 20 years), but the cabinet work to me is a PITA. I don't have a router, so I would have problems cutting the driver recesses.
