you have 2 main choices if you are wanting new top of the range markers this year
ego 8 (though from people i knows experience they are less consistent in terms accuracy, but incredibly effiecient, so you can just soak the area with paint and all will be good ... except your bank balance)
pm8 (yes pm!) it's £400 cheaper than a dm8, has slightly different milling, and is a bit less efficient, is incredibly accurate and is a very good marker.... a lot of my team have them now, and they run beautifully (though you need to keep the bolt well lubed else it starts to stick!)
though as probably said he before, all of this means nothing if it feels crap in your hand
personally i can't stand ego grips and have real issues consistantly keeping high rates of fire with them.. I feel much more at home with a UL frame, and so i go for DM/PM everytime.... but others i know are more than happy with egos, it's just a matter of preference with how they feel in the hand.... best thing you can do is spend the next couple of months going to walkons and or shops and trying markers, see which one fits you best, it's now down to you to try them out... then you can make up your own mind about which is the best marker out there (because its and entirely subjective view
)

and after re reading your original post
ego 7 ... less consistent, very efficient, any monkey can tech it
dm 7 ... more consistent, less efficient, any monkey that can read a manual can tech it
go try them out and see what you prefer
*the consistency acutally has very little in it, and as for the efficiency,... i doubt you'll notice it unless you're a back player taking a rediculous number of pods onto the field with you....
however the biggest difference is still how they feel in the hand... so go and try them!
