I had £20, and ordered 4 Chinese pens through e-bay using the Chinese section of this forum to work out which ones were likely to be good.
I got a Kagileu 356, which is proving to be a nice pen - lovely nib.
A couple of Baoer 388s which are pretty good. Better made than the Kagileu, but the nib on the Kagileu is substantially better.
A Hero 382 - which is nicely made, but it burping ink a bit. It's a nice pen, but I'll probably use it as a desk pen - as it's not travelling well.
