I have a largish 100MHz Tectronics 465B o'scope which I picked up at an auction for $100 back in 1990 when I worked in San Jose, California. It's my pride and joy as I use to use them a lot back in the '70's and '80's when I was in the Navy. However, it does take up a lot of desk real-estate, so I don't drag it out unless I really need too.
Earlier this year, Bitscope released a USB based DSO that you could run off a Raspberry Pi, MAC or a PC: http://www.bitscope.com/product/BS05/ Awesome, so a few weeks later it lobbed onto my desk for a play.
First thing, it's a tiny 20mm wide x 110mm long bare board that has been shrink wrapped in clear plastic. It takes a bit of getting use to and to gain confidence that it's reporting correctly what it should be.
I used it last night to monitor the noise on the Z-axis of my 3D printer:
The leads are of the grab claw type. Here I have them grabbing onto the bolt slot:
Here is an action screen shots of the software working on my PC:
I would recommend it if your in need of a cheep-ish o'scope.
