I've both a FEG and FM HiPower clones. Both shoot well and have been reliable. The FEG has a better finish. The FEG trigger is heavier but crisper, the FM trigger is lighter but creeps. Neither should be over about $350.
No experience with the CD HiPower clone. Has better safety lever and sights, but has gotten mixed reviews. I've a CD 1911 that has been very good approaching 4000 rounds thru it. A few minor problems initially that I easily fixed and should have been caught by QA QC if such can be done on a $400 1911. Over on 1911forum.com little good is said about CD customer service.
