iphone armband

What is the best armband for the iPhone 4?

I have spent the last hour and a half online searching for a good iPhone 4 (Verizon) armband. I do not want an armband where there are two pieces that snap together or whatever. I want one piece, I want it to have good reviews & I would love for it to be under $20 (US). There are a lot of reviews on the Belkins & NeoSports, but I just want a good one. Any reviews or advice from anyone?

They all do the same thing essentially. Ive used a few for the gym since i lost mine. Just ebay it. you will find a better deal there.
