Congrats on the new blaster sg3! I have no experience with the poly EAA guns, but am impressed with the EAA steel CZ clones so far. I've owned CZs, Tanfoglios and Sarsilmaz and all are good. I have not dug into the guts of a poly CZ or CZ clone, but if they are anything like the steel guns, it's pretty easy to clean the feel up by polishing the internals of a clone. Even if left as delivered, it's a pretty good deal for the money put out.
