I have just received my Xminilab from Gabotronics and am thrilled with it. It has a fairly limited bandwidth, but at $69 this is a fabulous tool for any makerspace and well worth a look.
from the site;
The Xminilab is a mixed signal oscilloscope with an arbitrary waveform generator in a DIP module. It measures only 3.3 x 1.75 inches, and can be mounted directly on a breadboard. The Xminilab can also be used as a development board for the AVR XMEGA microcontroller.
