I said this the last time this drop came up: This printer is not worth the price they want! Unless it comes pre-assembled, with an upgraded (safe) power supply, tested, calibrated, dual fire extinguishers in SLI, and an OnStar-like service for when it catches on fire.
Seriously though, you can find these listed on Craigslist or Ebay, pre-assembled and tested, for not much more than this $250 asking price. The biggest pain with these printers is that they take a long time (I mean like 8+ hours) to assemble for experienced tinkerers. On top of that, there have been serious, legitimate cases of the stock power supplies catching on fire.
These printers do have some decent upgradeability though, so I would only consider one of these if you like building complex machines and investing time and more money into making it better/safer before you will be able to print much at a high quality. It has a decent community on Facebook, but most 3D printing enthusiast groups just label it as a fire hazard.
For somewhere around $5-600 usd you can buy the printer that this is cloned from, the Prusa I3 with all tested components, a warranty (the A8 has no warranty), and all of the same upgradability and more.
