Can anyone help me here I trying to deside weither or not to buy a used v1 or just bite the bullet and buy a new v2.  But I really dont understand the differences between the two.   What are the pluses or miniuses.  I also thought that I read something somewhere that a v1 could be upgraded to a v2 for like $20.00.  If anyone had any other reasons that one version is better then the other I would love to hear from you.
