The M1245s are pretty neat. They are tiny, full body condenser mics at a great price. But, their low end frequency response is not as full ranged as their brother mic, the M1290. The M1290 is also a little longer, but still tiny compared to most any other mic.
There are a couple of people on this list who run the M1290s. I ran them once also and was completely impressed with the results.
I am sure you can find some samples of them.
