Omni-directional Mic in need!!!

Hey I just purchased a shot gun mic and that is GREAT for interview or close quarter quality sound. But of course the stereo mic on this camera is more than unworthy. My 12 year old camera MONO mic has a better mic than this thing! So I need some suggestions on an omni directional stereo mic that I can buy, below the $100 level, in fact it can be below $50 for all I care. I just want a mic that I don't have to scream from 5 feet away in order for it to pick up the sound. The quality doesn't have to be great either because I just want it for when I need to record something in my back yard and I need to hear all around me. I also want a mic that can pick up sound from a good distance (more than 10 feet away, so more like up to 100 feet). And of course when I research mics for camcorders all I can find are shotgun or lav mics so that doesnt help me. So please post some replys on some suggestions for a omni directional mic. Thanx

A 100'???? that's quite a distance. I think you are looking for a very sensitive mic. I bought some omni mics from Church audio on ebay. two omini mics, requires an external powered mic pre, about $150. I also have an audio technica stereo mic that I bought for about $30 that is stereo, not omni, but is pretty sensitive. Maybe not the best quality though. I also have a rode shotgun that works great. but picking up stuff at 100' away would be a challenge for any mic regarldless of price.

I beg to differ about that that 100 ft remark. Im not talking like you can hear dialogue clearly at 100 feet, but can pick up something from that distance. For example, you can hear a person yelling at 100 feet, or glass breaking. With thisi nternal mic right now oyu can't hear that.

But if you could give me a link to that $30 mic id appreciate that
