Ok. may be I will buy 200pcs(or more?) and mail them to VintageNut/USA, and VintageNut will mail 100pcs to Cerebus/Europe, or may be the other way round. I'll check which way is better(available postal, custom, pricing) tomorrow.
From my tests, 2DW232 or 2DW233 will do, the difference with others(2DW235, 2DW234) is only the nominal zero TC current, but I saw not very much actual difference, and the zero TC current of 2DW232 or 2DW233 are usually higher than nominal. The manufacture seems to mark the brand randomly.
