Which is most common PIC chip, after 16F628A?

I would not trust the chips sold by those sites. Most probably they are de-soldered from pcbs, tined and maybe remarked too so that they look brand new.

Yeah they are desoldered chips. I have bought 16F886 from taobao. Pack of 10 costed about $7 maybe. There all were 2nd hand, some even had some firmware in it and fuses set But they all work just fine so far. I'm using them during prototyping or not important projects. Genuine ones I buy at digikey.com
