12 bit ADC and 1024x600 touchscreen, $350 2ch/70MHz version, $400 4ch/70MHz, blows Hantek out of the water.
I think the 802/804 can be hacked to the faster 100MHz 812/814, but I didn't search for it.

Early tests show hacks are possible but they aren't perfected yet though I am sure there won't be a problem once there are enough oscilloscopes in peoples' hands.

Also thank you David for voicing your opinions of the DSO2x1x oscilloscopes.  I nearly bought one but held off to see if the firmware improved.  Now I have a Rigol DHO804 on the way.  You might consider adding a new first section to your DSO2x1x FAQ titled "Should I buy one?" with links to you and others saying "don't."

Anyway, in one respect the Hantek is unbeaten: it costs one third of a Rigol with AWG.
As problematic as it may be, no one has ever doubted the bandwidth or sampling rate as far as I know.
Unfortunately, the Hantek has no competition in terms of price and is therefore difficult to compare.

Dear friends, I need your help again.
I received a faulty (memory chip error) DSO2D15 and Hantek support instructed me to replace the W25N01GVZEIG. I bought some chips from AliExpress and now the plan is to: (1) desolder the old chip from the board, (2) sit/ solder a W25N01GVZEIG on a SOP8 board with pins, (3) prepare some sort of socket for this convertor I manufactured and (4) solder the socket with some wires to the motherboard to replace the original W25N01GVZEIG (David has done something like this using old MMC card and a MMC socket).
But now my problem is that I desoldered the memory chip from the board using hot air, but I managed to rip two of the pads which were used to connect the W25N01GVZEIG (attached), the corresponding pins are 7 and 8, on the left-down part of the empty place where the chip was.

Do you know any alternative locations on the motherboard where I can solder wires, i.e. where those 7&8 chip pins were going onto the board?

Many thanks for any ideas you would provide!

DavidAlfa:
Always poke the IC with the tweezers before trying to remove it, if not moving freely then more heating is required!
I disencourage doing the socket thing, I did in a time where almost nothing was knew about the scope.
I removed all that short after learning there's nothing important inside and no special procedures are needed for recovery.
Check the schematics, also this picture.

I did something similar to what you want to do in order to be able to quickly change memory chips during various tests or in cases of checking problematic dumps from members of the Russian forum. As it turned out, this socket thing does not work without any problems with any wires. You can solder everything correctly, but the scope will not boot, or after updating or using platform-tools, the scope stops working. Maybe I was just unlucky. The wires I use now without any problems are a set of breadboard jumper wires from Aliexpress. So I would not advise you to build such socket things.
