I fully agree. The disadvantage is that the screen is the smallest (all 8 x 10 div) among the 7000 mainframes:

Analog storage: 7613, 7623(A), 7633(A), 7834 - 0.9 cm/div
Non-storage: 7603 - 1.2 cm/div (the 10 x 10 div screen option has smaller divisions)
Other non-storage: 7XXX - 1 cm/div

The logic analyzers (7D01, 7D02) all have their own digital storage, so analog (CRT) storage is of no value, whereas at the same time, the smaller screen size of these analog storage 'scopes is a disadvantage.

Basically, what I'm saying is: Get a 7603 (preferably) or another non-storage mainframe for digital stuff and use the analog storage mainframe for analog stuff.
Obviously, with only one mainframe available, the screen size disadvantage becomes moot.

The analog storage mainframes are very convenient when using with non-storage spectrum analyzers (7L12, 7L13).

So, as you see, you need so much more equipment, which as you mentioned before, unfortunately isn't that easy to come by where you live.

By the way: The nice cursor measurements available with DM44-equipped 'scopes isn't available with e.g. a 7D15, although "gated" measurements are.
If you want something a bit like cursor measurements, you need a four-slot mainframe with e.g. a 7B85 / 7B80 time base combination, which gives you on-screen digital delta-time. Alternatively, a 7854 mainframe would help

You may also hunt for a filling panel for the time being...
