I felt exactly the same way, having doubts between the 140+20 tier or the digital 165 tier.
I really couldn't make up my mind, so I went for the $250 tier and got both.
A bit steep yes, but atleast I feel that my money goes towards something great, being this nostalgic and all.
God, I regret that I spent all those money on that Collectors Edition of Diablo 3, such waste...
