I purchased the Wittboy through Aliexpress complete with a receiver instead of a console for NZ$360. The recent rain gauge was from Amazon Australia for NZ$140. Amazon have a pretty extensive range of Ecowitt models. Watch out though, the prices are in Australian dollars and they add 12.5% GST on the invoice which is then subject to conversion to NZ dollars. I had a major holdup with NZ Customs here in Christchurch for the rain gauge, but received an apology from NZ Post, so importation shouldn't be a problem.
The current model receiver GW3000 is more advanced than than the GW2000 I got, in so much it takes an SD card which can still record data during power failures. The Ecowitt software is pretty impressive, so not having a console is no loss.

All in all, I'm very happy with the Ecowitt equipment.
