Recently I found in China a company i never heard of for folding bikes.
Bought already 2 pairs of 16".
First model was SKYLINE S-500 with Shimano FT30 cont nearly $200
second was DAZZLE S-500 which is the same model with rear suspension, I had to pay an extra of $10.
The quality is great, aluminum frame, good handcraft and light weight, about 11 Kg each.
The only problem is that the web site is only in Chinese, I don't know if you can buy them out of China. http://www.oyama.com.cn/
I think they offer great models as far as the 16" series.
I've noticed Oyamas here (Shanghai) -- mostly in Decathlon stores. They appear to be an excellent value for the money, even relative to local-market Dahons. At first I thought they were re-branded Dahons since many have a similar geometry and folding approach. The frames I have looked at have been well-made and well-specified for their price. But I haven't ridden one beyond the parking lot. Taiwan-based, they have a factory in Taicang, Jiangsu Province. Recently launched in Europe. Interested to hear any ownership experiences!
