  All scopes of all brands with sufficient bandwidth (HF response) will work, but almost everything 
other than HP, Tek, R&S exhibit excessive vertical amplifier DC drift (the trace moves up and down 
as it warms up and throughout the day) which will eventually drive you nutz.
The Tektronix units were extremely popular and are not rare in any way.  Most of these older units 
would be repaired with a parts donor.
