guys, i have an iPod touch and i want to be able to listen to things i record using VOICE MEMOS on my iPod. previously i was using my iPhone for this function because it has a built-in microphone. But i accumulated so many memos that it takes up so much memory on my iphone, so i need to get this stuff on my iPod. long story longer -- i'm looking for a good microphone that i can use with my iPod touch, (since there is no built in mic, i'll have to buy one)... can you guys recommend one? it doesn't need to be expensive. i'd like to stay South of 100$. i just want something that will record ideas, etc. and that i can listen to back on my iPod in the car, etc. thank you!
