Just received my Empire 4000d1 from Needlestein and must say he did an excellent job. Thank you Sir! From all the positive results and his willingness to share his experiences I believe Needlestein should have his own sticky where he can talk about the experience with each cart he retips. I doubt many would mind the fact he may be making a little side money. Big deal. Read back through all his posts and you might feel as I do and that is, he's earned a higher status than just a good AK'er. Knowing what works and what doesn't may save many of us from wasting time and money. And it would be easy to find. Thanks again and good job man!
