Well you say EC-635, but that's quite expensive compared to other acquisitions (the W-3, and additional UH-1H, and Nomads talked about).
The picture on that blog post seems to suggest the Fennec. It's still listed on the Eurocopter website, which suggest it's still being produced and marketed. So isn't that more likely than the EC-635?
With more Tigres coming on charge, don't forget about second-hand Gazelles. Just saying, no idea if that's an option. But refurbished, they may be a cheaper alternative to new Fennecs. Interesting, no?
