Why is it such a problem for "stand-alone" scope manufacturers to use 10- or 12-bit A/D converters? I have seen a few PC-based 10-bit units and a 12-bit one, as well. (They do it.)
There is a flood of inexpensive scopes even at the 200 MHz range (with all kinds of bells and whistles).
No way will I even consider upgrading my 20 MHz, eight-bit scope until I get more vertical resolution. Any thoughts?

There is a digital oscilloscope from Yokogawa that might fill your needs. The DL850 ScopeCorder will sample at 20 MHz with a 12 bit resolution. Since this is a modular instrument, you will need to select the components to fit your needs. See www.scopecorder.net.
