Let me put it as you simply as I can, first of all I have put a lot more into my first Gen than you.
Second I see no reason for me to sell it since I like what I did to it and I am satisfied with it's performance and looks.
Thirdly I will never in my life time get what I put in to it, so basically what I am trying to say it will stay in my possession till they day I die.
If it was me I would hold on to it and enjoy, only you and you alone can make that choice. Good luck on your choice.
