Sandisk Sansa M250,iAudio U2 or Creative Labs Zen Nano Plus are all good 'basic' 1 GB flash based MP3's.
All basically have the same features. Sansa does not support in-line recording. Sansa is only subscription enabled player of the three. May be minor other items.
I am not qualified to note if any one has substancially better sound that the other 2
I'm looking for a durable MP3 player for running min. 1G memory. I purchased the MSI 521 and loved it but after 9 months of heavy usage it is not working correctly.
I run 40+ miles a week with this thing through snow, rain and extreme cold or heat and I need an MP3 player that can hold up under these conditions.
From what I've heard from other runners the Ipod Nano is a little delicate for this type of use even with the waterproof case.
I would also like it to have an FM tuner.
Any suggestions?
