I enquired with the showroom in Plaza Singapura, last year, about their 905 SWC. The SWC is now out of production. Apparently, the camera in the showroom was the last one.
The salesman in the showroom did not appear to be interested in selling the gear and took a while before he put aside his newspaper. I think it is because they don't really encounter many people who are genuinely keen on purchasing a camera. I would have bought that 905SWC, but the salesman had to telephone his manager, and after a while, they decided not to sell it and wanted to retain it for their showroom.
Rather unfortunately, I have not bought any Hasselblad gear from Singapore; it would be nice to be able to support the dealers in Singapore. I found my XPAN II marginally cheaper in the UK. I bought the 905SWC from Yodabashi when I was in Japan. The 905SWC cameras are still available from the USA, so you may wish to explore that avenue. I am now in Melbourne and I have not seen any.
The Mamiya 7II rangefinder is also a very good suggestion, but I thought about the flexibility of a digital back with the SWC. I don't think it is possible to use a digital back with the Mamiya 7(?).
Whatever it is, I think these cameras are really great and will give you a tremendous amount of satisfaction. Good luck!
