Cheap Samsung NX lenses as spareparts

[Thanks to SpacemanUA for this informations: http://www.dpreview.com/forums/post/57042702 ]

Samsung provides very strange service and repair policy. They actually don't "repair" lenses if, say, something is wrong with motor or aperture unit (as Canon or Nikon does). They just replace the whole lens. For example, I had 45mm 3D lens that had oil on it's aperture blades. But service manual for this lens has only two parts: lens and lens mount. That's it, you can't buy aperture unit. Thanks no engineers, it has simple constriction, so I managed to disassemble it and clean aperture very easy. But, I digress...
You can buy "spare parts" in Samsung service or any website or shop, that sells it. And there is very interesting "part" called "ASSY BARREL TOTAL". It means complete lens. With caps. No hood. It will come in grey carton box with a limited warranty for a few months. And the price... Get ready to be surpirsed.
Here is a short list of models and corresponding part numbers. I won't post links, where you can buy it - just Google it. You can find another part numbers there and find the lens you need. I also post prices that are in list for today.

Following this thread, I found that this Australian site seems to have all the parts numbers:
