Unfortunately not for me, but a friend of mine is looking at a couple MP5 clones. The two he is primarily looking at are made by Zenith and PTR. The two models are relatively identical, and are within about $40 of each other in terms of price. Is it one of these brands a better choice than the other? Or is there another one in the $1700-$1800 price range that is worth considering over those two? Thanks in advance
