Sennheiser HD201 - HD212Pro - HD200 Master?

I am buying a new pair of headphones and I need advice. I am willing to pay around €50 / $60 for them.

They will mostly be hooked directly to the computer, and ones in a while I'll use them with a portable cd/mp3 player.

I am considering the following,
HD200 Master


Sennheiser HD 212


Sennheiser HD 201



I know the 201 is a lot cheaper than the others, but are the HD212Pro/HD200 Master twice as good as HD201 (they cost about the double)?

I am leaning towards the HD200, because I really like the way it looks. But will 64ohm be a problem for a ipod or other portable devices and the computer?

Thanks in advance
