Reasonably priced Russian hair?

I want to get extensions put into my own hair; only about 5-6 inches. It's more to add thickness than length, but would like some length added.

I was thinking of either buying nano tipped extensions or buying bulk hair and having them sent off to be nano tipped for me.

My hair is about 3 inches long so i'm worried it will look stupid. I can't cope with my receding hairline anymore.

Where can I buy either Russian or European hair that is reasonably priced?
