Just wait and see if AIM gets any Israeli Hi-powers in again...
I ordered one of the alloy frames and it literally looked like it had been thrown down a driveway, then got run over a few times. Then they had mkii and mkiii hi-powers and I ordered two figuring that the first one was just beat up because it was an alloy frame and that AIM wouldn't be charging what they were charging for run of the mill steel frames in poor shape, nope these were almost as bad. The kicker is I could have ordered from that one guy on Gunbroker who has actual pictures of what you are buying and mostly nice re-finishes for less so I guess in that respect it doesn't meet your "cheaper" criteria..
Oh, and that was with the handpick option on all three, at least they all functioned fine..
