Excellent read. I would agree with his comments on the Eis Sp, so probably agree on his M comments as well. I do think the M Perf would be better for me, but price is a big factor.
At the end of the day however, the M Perf would have cost me over $2k more than what I paid. So until they come down big time in price, I'll stick to what I have and be happy
