Congratulations you're coming home! Hope you're planning on staying, I think you've done more than your service to this country & those of us in it! THANK YOU!
There are plenty of growers that have kovachii, just depends what size you want & your budget.
Since you have limited internet access I'll get right to it. You can get Phrag kovachii from Glen Decker at Piping Rock Orchids http://www.pipingrockorchids.com/ or Jerry Fischer at Orchid Web http://www.orchidweb.com/default.aspx. Glen Decker's site has info on how to grow this species.
