Personally I had the 06 ego and the etek felt more comfortable. I don't know what you mean by ups? the 06 is no different internally to the 06 with the exception of a qev. You won't notice the difference anyway unless you plan on shooting 25 bps + anyway.
Etek, and spend the rest of your money on paint.
Or go and buy an 07, which supercedes all others!!!
