I'd have to look at the design! it surely looks interesting!
By the way are you a hobbyist or pro? or both?

Hi Niklas-
I thought this is an interesting project and actually looked into obtaining
parts, not too bad.  I'd even be interested in sharing the cost of getting a
board made.

DSO Specification
                        The DSO has the following specification, this is
likely
to change significantly as the project is further developed.

            Channel Spec
                           1.6MHz to 50MHz sample rate
                           8 Bit resolution
                           3MBit sample depth
                           Analogue and digital capability
          Operating Modes
                           Dual channel (2 analogue channels)
                           Single channel (double speed and depth, i.e.
100MHz
& 6MBit)
                           Logic analyser (16 digital channels)
                           Mixed mode (8 digital & 1 analogue channel)
             Triggering
                           Variable pre-trigger
                           Variable edge trigging threshold
                           External trigger input
                           Logic analyser triggering
             Software
                           Fully GUI driven
                           Full control of hardware from software
                           Zoom & Pan functions
                           Trigger level & point indicator
                           CSV export function
               Misc
                           Flexible design allows for expansion and bug
fixes
without hardware modification.
                           ISP (In System Programmable)
