What do you need ?

What frquency range ?
What bandwidth ?

What are you going to use it for ?

I usually use micros and similar boards up to 100MHz
so ended up buying two second hand scopes and a usb  based logic analyser.

The one I use most of the time a HP 54502A
dual channel 400MHz dso.

One I use only when I need to debug something
higher than 200MHz  HP54501  1GHz quad channel scope.

Logic analyser  great when debugging micros.
easy to use and easy to carry.

good for up to around 100MHz.
I use this a lot. Windows software only though.
Still waiting on them to release their api
so you can call it from your own software.

What I find is it is usually easier to have equipment that doesn't need 
a computer.
Hit the switch and it is up and running.
Can have hassles with usb based equipment especially if other devices 
your using use
 the same manufacturers device but with a different driver or different 
driver version.
