Watch used 210s.. Tektronix recalled a huge lot of them (I think almost all
of them) last year as the connection to ground was breaking off inside the
scope (Yikes!). Also, the 210 has a shitty display like my THS720A... it is
LCD and rather fast changing waveforms can look like a band of black on the
screen (very annoying).. The price is right and the storage is nice but the
display is not anywhere near as nice as a CRT.

Best thing to do is go to your local Tek dealer and try out a TDS210 and a
CRT model (maybe even a 694C ;-) ).. See which one your comfortable with
and then buy used if you don't want to spend the bucks.

I don't recommend throwing away a few hundred dollars on an old piece of
junk... you just might get another PDP-8 to fix! ;-)
