some mp3 player questions

[groovypanda]

thinking of getting an mp3 player so would appreciate some views on the following:

1) what are the best mp3 players out there - apple, creative etc?

2) will i be able to play my collection of mp3's d/l through soulseek etc? (i understand sony players have copy protection on them)

3) on a similar vien what can you load onto an ipod - is it just ripped cds from your own collection and stuff bought from the itunes shop..?

4) any other considerations i should bear in mind?

i'm probably looking to spend up to £200

thanks for your help
