Just a comment upon the Second quality components showing up in new builds. I believe that to be more common in the last year or two. It has become a genuine problem tho and now it is difficult to know who to trust [with as much verification as possible] and who is in it for the short haul to make max money and then move on. I got stung with a great looking machine which was generally very well built but with two Reci tubes [R2 andR6] that the beam was not good enough to use. I think the CO2 tubes are most commonly substituted with seconds and they are fairly expensive and it is very difficult to actually pin down a badly performing tube. A power supply being slightly off would probably be much harder to detect. I have also been burned by Sign-In-China.com on yet another R6 Reci reject tube.

Please leave any comments that might help people down the road with buying decisions. The bottom line when dealing with Chinese companies is that you are taking a risk but I like to know what the risks actually are. Thanks Gene
