SG2 Resin kits not avail in US

This reminds me...

A few of the SG2 resin kits I may like to get someday are not listed on
the GeoHex site.

Are these still avail. through GeoHex and just not on the site?  

Must I order these directly from the UK via GZG?

Or am I just screwed because of some 'exclusive' deal GeoHex has on US
sales?

Thanks,
SC
