Sadly they're upgrading the Hawks instead of replacing them (I think it would be fair to say that the dozen hours I've got in them are probably about the most fun I've ever had at work).
There's a PC7 Mk2 which is semi-glass-cockpit + HUD for sale for about US$2m at the moment, but I think you might get the older Mk.1 for about half that if one comes up.
Pretty innit
