I recently purchased a Hantek DSO1000E Series and while it was a great price and it seems well built, the software is very buggy (frequent rebooting, slow response and persistent video overlay bugs) and forget about manufacturer tech support. It would not pass self calibration and the upgrading to the latest firmware (2016) only seemed to make things worse. I didn't receive a reply from two emails after a week but I did receive a brief reply on their forum.
Luckily I purchased it from a US supplier so I have the option to return it and probably go with another brand.
