What probes for a 400mHz HP54504A with 7pF input capacity?

[Peter_O]

I could not resist to rescue a 400Mhz HP54504A digital oscilloscope in best shape for 160 Euros.
It comes without probes.
I'd like to have dedicated probes for this one. I do not need to use the highest freqencies and probe budget should be in some kind of relation to the sum above.

Input capacity is 7pf acc. to datasheet:
www.testequipmenthq.com/datasheets/Keysight-54504A-Datasheet.pdf

The compensation range of many budget probes like testec 312 HF seems to start at 10pF.

Does anybody has a recommendation of good budget probes?
