Here's my 2nd payment proof from Bux.gs, 55+ USD:

There's still many of these PTC sites, but beware, some are scams, be sure so check its forum/proof of payment. Best to do a search over Google with keyword like: 'sitename' review.

Btw, you can check my affiliate of some PTC sites which I'm participating myself, most just started, bux.gs is the first of them that I requested/received payment. A very good PTC site.
