I went for a PC based scope. I'm an electronic engineering student and wanted a portable solution. I got the Picoscope 2206B. 50 MHz bandwidth, 500 MS/s, 32 MS buffer and a arbitrary waveform generator.
As a first scope, and as a student, I'm thoroughly pleased with mine. The Picoscope 6 software is great too as it includes a decoding feature for things like I2C, SPI etc.
