I got a deal with a regular RS 32 (tilt-swing) + 70 + WRS 1600 + plate for $8,500. Not saying who sold it but if anyone doesn't believe me I can send proof. Not looking to do the 645 equivalent of paying $4,500 for a GFX 100. Thanks.
There's a fine line between the products and their prices. Cambo non XT is the cheap entry point into tech cams and the deal you cite is maybe 2.0-2.5k below market if one would usually pay 5.5-6k, 2.5k and 1.5k for the items, respectively. That's in the range of what is known. But then your stuck with Cambo. These items can be 13 years old ... and it is not uncommon to get a little discount if one buys multiple items of which two are harder sells (70 and WRS).
XT is another ballgame. Came out in 2019, x-shutter, expensive and rare on the 2nd market. Also prices vaey strongly by lens. The 32 is a great one, the 70 is not expensive even new today and can be actually had for as low as 1.5k if you get a magenta band. And Cambo cams have always been on the budget side being priced lower than both Arca and Alpa with very low resale value as a result.
So sorry to break it to you - it is not exactly the deal of the century you've made there - a fair deal for some difficult to sell Cambo things, yes, but it doesn't mean that everyone will fork over the hottest current warez at a discount because you shout loud for it and got yourself a WRS1600.
I am sure your are not at risk of being "scammed" by being "highballed" given your acute view on "market" prices.
