Is there an inexpensive DMM with FAST MIN/MAX (NOT just MAX) function?

Adam Baum:
Question in thread title.
bdunham7:
Sure.  How fast and how inexpensive?  You'd need to quantify those attributes to get a meaningful answer.

Hello,

The (old) ut-61e has min and max values.
The value read is a very fast transient, not the average over a period (0.5s).  I read about 20A or 30A when charging a 4700 µF capacitor with a laptop-type power supply (36V - 4A).
Fungus:
What bdunham said, and:

What sort of signal are you looking at? What time frame?

You can get pocket oscilloscopes for about $30. They have very fast min/max over short periods of time.  :)
RtBNL:
Both the Brymen 869 en 789 have a very fast min/max (crest function) they both measure the peaks op(~+ & - 325v] on the wall outlets that give ~230 volts.
