There are huge price difference but seems codes are similar and specs are same.What do you think about them?
Thanks in advance.

I have several transistor testers..... including DUOYI. The DUOYI wiill do a good job. Also, you might look for the Atlas brand made by PEAK electronic design ltd.
It is fast and automatic. It will also identify which lead is the e-b-c or s-g-d.
