If it is analogue signals, you need a bandwidth of about 5 times your max frequency you want to measure. Digital signals you need about 2 times unless you want to do glitch capture. Something that can do a waveform capture is always good. Personally I prefer HP/Agilent, but I have a Tektronix scope DSP360 ($4000) . The FLUKE Scopemeter series is not to bad if you want portable and rugged. Stay away from anything less than 50 Mhz. Look on Ebay, there is normally a lot of units available.
