A hint for you:
I have used an Tektronix oscillioscope with 16 channels of 2Gsamples/s that
have a color screen and a standard VGA outlet on the back in case you need a
bigger screen.... it also has a 3.5 inch floppy to store the waveforms at and
you can print them too.... oscillioscopes isn't what they used to be :)
These portable LCD scopes are really usefull and certainly fill their part of
the market. You can't compare them with the real thing, but then it wouln't be
fair to compare your portable Fluke with a desktop precision multimeter either.
The LCD isn't really that big problem.
