About a year and a half ago, I bought the completed Cushman MG-34 with the bipod. Even though it was supposed to be "finished", it really took a LOT of work to redo (body filler, sanding, painting, weathering, etc.). I definately was disappointed when I first saw it. After all the work, it came out good enough for trooping and I was asked many times if it was a real gun (believe it or not), however the viewing distance was about 8 ft.
One good point is that it is VERY light weight for trooping and transport. Another good point was that Cushman was good to deal with and I got the MG-34 when promised.
I have replaced it with the far more accurate Hyperfirm MG-34, which itself required a LOT of work to get accurate and looking good, up close. I probably put over four times the money, and time, into preparing the Hyperfirm than I did into the Cushman.
It really depends on what you are after. I think the Cushman was about $140 and the Hyperfirm was just over $600.
