Topic: AKG D190C a buy?

[kuuan]

I have an offer to get two AKG D190C in very good condition for 40 Euros ( as the óffer stands =  50+ US$ )
does anybody know this mic? are they a buy, good mics to experiment with?
so far I have found out that they used to be quite famous reporters mics.

however those are condensers, aren't they? What is the minimum requirement for a preamp to do them justice?
I only have a very simple selfmade one discussed in this thread: http://taperssection.com/index.php?topic=71782.0;all and I am afraid that it won't do the trick.
