New ? No Chance....
Best offer until now :
Micsig CP2100B, 1.5Mhz for appx 375€.
Actually I got this and it´s surprisingly good for it´s money.
The only thing you can do, and with a little bit more money than 200$, is looking at ebay or similar platforms for a good old tektronix probe+amplifier.
The A6302 probe got 20Arms/50Apk, a Bandwith up to 50Mhz (?), the probe amplifier AM502B for example allow range steps down to 1mA (!!!).
As I am very confident with the micsig, when I get the chance, I would buy the tek also.
It got degaussing function and compensating measure method - This you´ll find only in actual models from up to 3000 bucks and more.
