Sounds like the Church Cardioids would suit your needs.
How much are you looking to spend in total? The Church Cards are $120 (I think). Don't buy anything thats too cheap because you most likely won't get great recordings.
You stealthing I guess?
Your best bet is to get a cheap Hi-MD recorder (maybe about $50) and Churc mics. If you can afford it, get the Church battery box for $40, but its not essential.
There's tons of threads on Church mics, take a search and read about them. You'll find lots of samples too.
