Sound professionals (a new jersey firm I think) produce a neat little T bar mic with minidisc size jacks which has got exceptional capabilities and cost $49 plus postage ($27 to UK). They describe it as a Single Point stereo Omnidirectional "T" microphone which a few people I know have used for old time sessions - and its very good.
