Check out the studio projects stuff, they make very good condensers for a superb price (poor man neumanns

)
If you would like a small diaphragm you could check out the C4 - a matched pair is about 280 EUR, they come with 2 interchangable capsules (omni, cardiod)
or go for a large diaphgram like C3 - dual membrane, 3 patterns, high pass, pad .... sells for about 270 EUR in the EU.
I have two B1s and a T3 tube mic from them and they rock for that price
