Definitely no on 14 or 7 unless you get a permission from who knows where, I am not expert in the matter.
To my best knowledge the housing & optics must be non-ITAR and the tube be Gen0/1/2 with photocathode response below 350 and FOM below 1200. Don't quote me on that, but that's how I remember reading it.
A loaner old Gen2 would probably be the only reasonable option unless you find yourself a way for a license or there's an exemption for temporary export. Edit: because, define cheap. Any system close to FOM1200 even with just 350 PR will be somewhere around $2K new. As an example SNR of 18 and resolution 64lp/mm. Would work relatively good in many environments over starlight illumination levels.
Best bets are to not take NV with you at all, purchase the NV from the destination or ask a lawyer.
