John,
There's also the Type 1A2 that is roughly the same thing as a Type CA in terms of functionality (quite a bit wider bandwidth though). I have one that came with my Type 547 estate sale find, and I'm really not using it much. Would consider a trade for other stuff. :o)

The 1A1 seems good for most use cases. mine is "The third model, from ???
until the end has four-sided V/cm knobs and a FET front-end."
1A4 seems good for emulating Jim Williams with lots of traces displayed...
1A5 seems like a fine one, and can use the P6046 diff probes, (but I'd have to
do the cal for P6046, which is long and detailed, and I have P6046's already
matched to amps that stay together and work in any scope.)
1A7A would be nice -- same features as 7A22, more sensitive than the 1A1...
