I'm looking for something to use while mowing the lawn(s) or shovel the snow with.. Sometimes, when mowing the lawn, it can take me up to 4 hours so I have to take that into consideration for disk space and battery life. But it's not really critical to me that it's feature rich. I'm having trouble justifying the expense, so it has to be realtively cheap...

Anyone have any models in mind? Maybe something I could find on eBay?

PS - Anyone who hasn't tried noise cancelling headphones HAS to give them a try!
