Thanks for the info. When I was searching for analyzer, I read some old posts here and another photo forum. The key reasons that I decided on this one:
1. It has the functions I need;
2. It is digital/LED, same style as the Jobo processors I have. It was also marketed by Jobo;
3. It has built-in timer. This saves me some room;
4. This analyzer comes with probe, manual and case, in excellent condition, at a price I can't refuse.
The previous owner is very experienced with this device. I can always ask him questions. I heard about Frances and read her book on large format. I'll do some homework and take advantage of it.
