I can't see any problem on handling the 2nd hand dealing by ching...I also met many rediculous guy before which make me bety angry also...not buy just ask, suddenly 放飛機 and "inch" me price too high etc . But dealing with those guys also an experience for me during these years and I will treat it as 一笑置之……As i known ching for a long time who is decent and very experience...really hope u can stay in the sharing forum....
