   You might want to consider something like this... It's 100Mhz. There
   are many of these from many different manufacturers. I can't speak for
   this one personally but showing this for reference...

     Thanks Gene.
     What I really need these toys for is, to check the video signal's
     sync pulses,
     amplitude, shape and polarity.
     Most of the time I would use these for to check audio signals.
     Do these have X and Y direct inputs, like the analog scopes do?
     I don't have room for large boxes anymore, like this
     Tektronix 7623A 100 Mhz Storage scope, I used to have in my shop.
