Thanks for the welcome and advice everyone.
I'll be sure to look around the forums before settling on a device to get. My requirements are fairly simple, cost is important unfortunately, I do not want to be tied to a specific on-line store and as few DRM restrictions as possible.

But I'll get into this later in the proper sub-forum
