I'm looking to purchase a voice recorder to take to fiddle camps. Have just started researching.

A think a USB capability would be a useful feature. One model I'm looking at mentions an SD card; don't know what's used if there is no SD card; what the alternative would be. I believe the sd card would increase recording time.

I'm looking at 2 Sonys, both for $159, don't know if I should mention models. They are ICDTX50 with 4gb. The other is ICDXX712.

I wonder if a USB port is not mentioned, does that mean it doesn't have it?

I'm really new to this computer/electronics world but am learning fast.

Thanks for any help. Don't know if any of this makes sense.
