I would take the 475... again
.
As you can see it is really small (left 475, right top 2215A).
But of course these are over 30 years old now. It depends of the conditon of the 475. You might consider to go for a newer one. The 2336 is not much younger (and I wouldn't like the swing down cover too).
The 475 has nice display illumination, but I prefer the brighter display of my 2215A (which has only 60MHz but some nice features as seperate brightness for A and B sweep and trace separation).
If you can, try both out, watch videos of them beeing used or wait for other offers. You also need a little luck to get a good one
.
Dave has two videos of the 2225 and this looks ok too .
EDIT:
Have an emc mesh filter in front of the 475 display, this is why it's so dark
.
And yes I agree, the 465B is also very nice
and would be a good option.
