Seb, you are going too fast again, but that's because of your age... you'll cure about it after 30. The toy you have pointed at isn't an 1MS/sec, but 1MHz analogic bandwith which is totally different. Take a look to the schematic, try to understand it and you'll see that is less than 500Ksample/second (my appreciation is 200Ksample per second.
A decent analogic tektronix of about 100MHz analogic bandwith has exactly the same price...
