eteks are considerably cheaper than egos, so i'm pretty sure give it 6 months, and it'll be pretty common, especially when resell values drop - i'm ready to trade my cocker for one!
i would imagine cockers will just drop even further in value due to the eteck coming out. the ego made it drop so a cheap ego will just bring the prices right down
that's the bad thing about cockers, but i'm going to get blackbean (ul conversion guy) to do some work mini'ing and half blocking my cocker, and fitting breakbeam eyes, that should spice up a trade a fair ammount - i might not even trade
