Recommendation on cheap Chinese Android phone?

Looking for something cheap. There's a plethora of no-name Chinese Android phones, but digging through them is not easy.

My requirements:

- penta-band HSDPA if possible. Second choice would be 850/AWS/1900/2100 bands support. Seems like most of them have only dual-band 900/2100 as 2100 is the common 3G frequency used in Asia.

- 1GB RAM. Since cheap is the theme, most cut the RAM to 512MB. There are even quad-core phone with only 512MB RAM.

- Jelly Bean.

Any ideas/recommendations? With links would be great.
