A storage - normalizer would also be a good addition to your 8754A.
However, between the cost of the test set and a normalizer, you might be approaching the cost of moving up a notch or two - say to an early 8753 or maybe one of the 8711/12/13/14 series.
You might be able to sell the 8754A to get a little seed cash to get the process started.? A newer instrument will have a lot of attractive features - greater dynamic range, calibration capability, digital trace storage, hard copy output capability, connection to John Miles software, etc.
