Hello from Germany,
RoG's NH90 kit in 1/72 is several years OOP. The kit can be found on eBay, and sells for round about 20 US$ (You know how eBay prices vary).
It is a very good replica of the prototype as it looked in the mid-90es: fine, recessed panellines, a cockpit with 3D instruments and all controls, good cabin detail with nice seats, only a cabin roof is missing. Fit of parts is komplex (due to ext. shape) but good. Wheel wells are detailed, the tail can be folded. Decals are for a Prototype (Le Bourget, 1991), fictional French and German army variants and a Dutch UN helicopter.
So
