A nice LDC that can sometimes be found in the US for about US$600 is the Beyerdynamic MC740. A very under rated mic IMHO. The MC840 is the transformerless version of the mic and it sells in the US for more than the 740, but less than $1000. A cardioid only version is the MC834, which can be had for around $600 also. These are all prices for used mics.
The only problem with these mics are they are relatively scarce in the US, so it is hard to find used ones for sale here. Perhaps you would have better luck finding them in Europe.
