You can always just pop in a music shop, like UPE in 5 R Vagnera iela, Old Town, Riga, LV-1050, Latvia ( +371 67 226 119) and get your own kokle there on the spot. It's going to be a bit more expensive than ordering directly from a kokle maker, but if you are in a hurry or you like to check out which kokle appeals to you more by the timbre and looks, it's a great option. I bought mine there in 2008 and several kokle students that I've had over the years also have bought their kokles there.
Another option, which is best if you don't live in Latvia or you want a custom kokle, is to order it from a kokle craftsman. Below is the contact information for a few kokle craftsmen from Latvia I'm lucky to know about.
As long as I know, even the ones who don't speak English, have solutions for translating, so the language is not an obstacle.
