Sounds a bit on the high side.
You don't need the Cambo view hood, Wista's own screen is excellent so a Beattie screen's not needed, and a 210 is quite a long lens for a standard, a 150mm is better. The dark-slides are also expensive.
I've been using a Wista 45DX since 1986 and they are nice cameras
There's better bargains to be had for a complete 5x4 kit.
